[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-22241 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of one aspect of the present invention is to provide an electronic component that can achieve a high self-resonant frequency while also achieving a high Q value. [Means for solving the problem]

[0005] (1) An electronic component according to one aspect of the present invention comprises a base body and a conductor disposed within the base body, the conductor having a first end and a second end in a cross section perpendicular to the extension direction of the conductor in a width direction when viewed from the extension direction, the first end forming a first angle and the second end forming a second angle, the first angle and the second angle being different.

[0006] In an electronic component according to one aspect of the present invention, a first end and a second end of a conductor form a first angle and a second angle, respectively, and the first angle and the second angle are different. In this configuration, for example, by increasing one of the first angle and the second angle, a high Q value can be obtained. In addition, in the electronic component, for example, by decreasing the other of the first angle and the second angle, the stray capacitance between the conductor and other components can be reduced. This allows the electronic component to have a high self-resonant frequency.

[0007] (2) In the electronic component of (1) above, the first angle may be greater than the second angle. With this configuration, a high Q value can be obtained.

[0008] (3) In the electronic component of (2) above, the first angle may be equal to or greater than 60°. With this configuration, a high Q value can be obtained.

[0009] (4) In the electronic component of (2) above, the second angle may be less than 60°. This configuration can reduce stray capacitance between the conductor and other components, thereby increasing the self-resonant frequency of the electronic component.

[0010] (5) In the electronic component of any one of (1) to (4) above, when a current flows through the conductor, the current distribution at the first end may be higher than the current distribution at the second end. In this configuration, by making the first angle larger than the second angle, a high Q value can be obtained.

[0011] (6) In the electronic component of (2) above, the conductor may have a first surface and a second surface connecting the first end and the second end, and at least one of the first surface and the second surface may be curved. In this configuration, by curving the first surface and / or the second surface, the angle of the end can be made small (pointed). This can reduce the stray capacitance between the conductor and other components. Therefore, the electronic component can achieve a high self-resonant frequency.

[0012] (7) An electronic component according to one embodiment of the present invention comprises a base body and a conductor disposed within the base body, the conductor having a first end and a second end in a width direction when viewed from the extension direction in a cross section perpendicular to the extension direction of the conductor, the first end having a first taper rate set based on a ratio between a thickness of the conductor and a first distance from an end of the first end to a position at a distance of 1 / 2 of the thickness in the width direction, and the second end having a second taper rate set based on a ratio between a thickness of the conductor and a second distance from the end of the second end to a position at a distance of 1 / 2 of the thickness in the width direction, the first taper rate and the second taper rate being different.

[0013] In an electronic component according to one aspect of the present invention, the first end and the second end of the conductor have a first taper ratio and a second taper ratio, respectively, and the first taper ratio and the second taper ratio are different. In this configuration, for example, by increasing one of the first taper ratio and the second taper ratio, a high Q value can be obtained. In addition, in the electronic component, for example, by decreasing the other of the first taper ratio and the second taper ratio, the stray capacitance between the conductor and other components can be reduced. This allows the electronic component to have a high self-resonant frequency.

[0014] (8) In the electronic device of (7) above, the first taper ratio may be greater than the second taper ratio, which makes it possible to obtain a high Q value.

[0015] (9) In the electronic device according to (8), the first taper ratio may be 55% or more. With this configuration, a high Q value can be obtained.

[0016] (10) In the electronic component of (8) above, the second taper ratio may be less than 55%. With this configuration, it is possible to reduce stray capacitance between the conductor and other components. As a result, the self-resonant frequency of the electronic component can be increased.

[0017] (11) In the electronic component of any one of (7) to (10) above, when a current flows through the conductor, the current distribution at the first end may be higher than the current distribution at the second end. In this configuration, by making the first taper ratio larger than the second taper ratio, a high Q value can be obtained. Effect of the Invention

[0018] According to one aspect of the present invention, it is possible to achieve a high Q value and a high self-resonant frequency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicated explanations will be omitted.

[0021] [First embodiment] As shown in FIG. 1, a coil component (electronic component) 1 according to the first embodiment includes an element body 3, a first external electrode 5 and a second external electrode 7 arranged at both ends of the element body 3, and a coil 9.

[0022] The element body 3 has a rectangular parallelepiped shape. The rectangular parallelepiped shape includes a rectangular parallelepiped shape with chamfered corners and ridges, and a rectangular parallelepiped shape with rounded corners and ridges. The element body 3 has, as its outer surfaces, a pair of end faces 3a, 3b facing each other, a pair of main faces 3c, 3d facing each other, and a pair of side faces 3e, 3f facing each other. The facing direction in which the pair of end faces 3a, 3b face each other is a first direction D1. The facing direction in which the pair of main faces 3c, 3d face each other is a second direction D2. The facing direction in which the pair of side faces 3e, 3f face each other is a third direction D3.

[0023] In this embodiment, the first direction D1 is the longitudinal direction of the element body 3. The second direction D2 is the height direction of the element body 3 and is perpendicular to the second direction D2. The third direction D3 is the width direction of the element body 3 and is perpendicular to the second direction D2 and the first direction D1.

[0024] The pair of end faces 3a, 3b extend in the second direction D2 to connect the pair of principal faces 3c, 3d together. The pair of end faces 3a, 3b also extend in the third direction D3 (the short side direction of the pair of principal faces 3c, 3d). The pair of side faces 3e, 3f extend in the second direction D2 to connect the pair of principal faces 3c, 3d together. The pair of side faces 3e, 3f also extend in the first direction D1 (the long side direction of the pair of end faces 3a, 3b). The principal face 3d can be defined as a mounting face that faces another electronic device (for example, a circuit board or an electronic component) when the coil component 1 is mounted on the other electronic device.

[0025] The element body 3 is constructed by laminating a plurality of dielectric layers (not shown). Each dielectric layer is laminated in the second direction D2. That is, the second direction D2 is the lamination direction. The element body 3 has a plurality of laminated dielectric layers. Each dielectric layer is constructed, for example, from a sintered body of a ceramic green sheet containing a dielectric material (dielectric ceramic such as BaTiO3-based, Ba(Ti,Zr)O3-based, or (Ba,Ca)TiO3-based). In the actual element body 3, the plurality of dielectric layers are integrated to such an extent that the boundaries between the layers are not visible.

[0026] 1, the first external electrode 5 is disposed on the end face 3a side of the element body 3, and the second external electrode 7 is disposed on the end face 3b side of the element body 3. In other words, the first external electrode 5 and the second external electrode 7 are positioned apart from each other in the opposing direction of the pair of end faces 3a, 3b (first direction D1).

[0027] The first external electrode 5 is disposed on one end face 3a side. The first external electrode 5 includes five electrode parts, namely, a first electrode part located on the end face 3a, a second electrode part located on the main face 3c, a third electrode part located on the main face 3d, a fourth electrode part located on the side face 3e, and a fifth electrode part located on the side face 3f. The first electrode part, the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part are connected at the ridge part of the element body 3 and are electrically connected to each other. The first external electrode 5 is formed on five faces, namely, one end face 3a, a pair of main faces 3c, 3d, and a pair of side faces 3e, 3f. In the first external electrode 5, the first electrode part, the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part are integrally formed.

[0028] The second external electrode 7 is disposed on the other end face 3b side. The second external electrode 7 includes five electrode parts: a first electrode part located on the end face 3b, a second electrode part located on the main face 3c, a third electrode part located on the main face 3d, a fourth electrode part located on the side face 3e, and a fifth electrode part located on the side face 3f. The first electrode part, the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part are connected at the ridge part of the element body 3 and are electrically connected to each other. The second external electrode 7 is formed on five faces, namely, one end face 3b, a pair of main faces 3c, 3d, and a pair of side faces 3e, 3f. In the second external electrode 7, the first electrode part, the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part are integrally formed.

[0029] The first external electrode 5 and the second external electrode 7 contain a conductive material (for example, Ag or Pd). The first external electrode 5 and the second external electrode 7 are configured as a sintered body of a conductive paste containing a conductive material (for example, Ag powder or Pd powder). A plating layer may be formed on the surface of the first external electrode 5 and the second external electrode 7. The plating layer is formed by, for example, electroplating. The plating layer has a layer structure consisting of a Cu plating layer, a Ni plating layer, and a Sn plating layer, or a layer structure consisting of a Ni plating layer and a Sn plating layer.

[0030] As shown in FIG. 2, the coil 9 is configured by electrically connecting a first coil conductor (conductor) 11 and a second coil conductor (conductor) 13. The first coil conductor 11 and the second coil conductor 13 are electrically connected by a connection conductor 15. The first coil conductor 11 constitutes one end of the coil 9. The first coil conductor 11 is exposed at an end face 3a of the element body 3 and is connected to a first external electrode 5 (first electrode portion). The second coil conductor 13 constitutes the other end of the coil 9. The second coil conductor 13 is exposed at an end face 3b of the element body 3 and is connected to a second external electrode 7 (first electrode portion).

[0031] The first coil conductor 11, the second coil conductor 13, and the connecting conductor 15 are made of a conductive material (e.g., Ag, Ni, Cu, etc.) that is typically used as a coil conductor. The first coil conductor 11, the second coil conductor 13, and the connecting conductor 15 are formed as a sintered body of a conductive paste containing the above-mentioned conductive material.

[0032] The first coil conductor 11 has a first conductor portion 11A, a second conductor portion 11B, a third conductor portion 11C, and a connecting portion 11D. The first conductor portion 11A, the second conductor portion 11B, the third conductor portion 11C, and the connecting portion 11D are integrally formed (molded).

[0033] The first conductor portion 11A extends along the first direction D1. The second conductor portion 11B extends along the third direction D3. The third conductor portion 11C extends along the first direction D1. An end portion of the first conductor portion 11A on the end face 3b side is connected to an end portion of the second conductor portion 11B on the side face 3e side. An end portion of the second conductor portion 11B on the side face 3f side is connected to an end portion of the third conductor portion 11C on the end face 3b side. In this embodiment, the length of the first conductor portion 11A is longer than the lengths of the second conductor portion 11B and the third conductor portion 11C. The length of the third conductor portion 11C is longer than the length of the second conductor portion 11B.

[0034] The connection portion 11D is connected to an end portion of the first conductor portion 11A on the end surface 3a side. A part of the connection portion 11D is exposed at the end surface 3a. The connection portion 11D is connected to the first external electrode 5 (first electrode portion). As a result, the first coil conductor 11 is electrically connected to the first external electrode 5.

[0035] The second coil conductor 13 has a first conductor portion 13A, a second conductor portion 13B, a third conductor portion 13C, and a connecting portion 13D. The first conductor portion 13A, the second conductor portion 13B, the third conductor portion 13C, and the connecting portion 13D are integrally formed (molded).

[0036] The first conductor portion 13A extends along the first direction D1. The second conductor portion 13B extends along the third direction D3. The third conductor portion 13C extends along the first direction D1. An end portion of the first conductor portion 13A on the end face 3a side is connected to an end portion of the second conductor portion 13B on the side face 3e side. An end portion of the second conductor portion 13B on the side face 3f side is connected to an end portion of the third conductor portion 13C on the end face 3a side. In this embodiment, the length of the first conductor portion 13A is longer than the lengths of the second conductor portion 13B and the third conductor portion 13C. The length of the third conductor portion 13C is longer than the length of the second conductor portion 13B.

[0037] The connection portion 13D is connected to an end portion of the first conductor portion 13A on the end face 3b side. A part of the connection portion 13D is exposed at the end face 3b. The connection portion 13D is connected to the second external electrode 7 (first electrode portion). As a result, the second coil conductor 13 is electrically connected to the second external electrode 7.

[0038] The connecting conductor 15 connects the third conductor portion 11C of the first coil conductor 11 and the third conductor portion 13C of the second coil conductor 13. The connecting conductor 15 is disposed between the end of the third conductor portion 11C on the end face 3a side and the end of the third conductor portion 13C on the end face 3b side. The connecting conductor 15 is, for example, a through-hole conductor.

[0039] The first conductor portion 11A of the first coil conductor 11 and the first conductor portion 13A of the second coil conductor 13 are arranged to face each other in the second direction D2. That is, the first conductor portion 11A and the first conductor portion 13A overlap when viewed from the second direction D2. A part (end) of the third conductor portion 11C of the first coil conductor 11 and a part (end) of the third conductor portion 13C of the second coil conductor 13 are arranged to face each other in the second direction D2. That is, when viewed from the second direction D2, a part of the third conductor portion 11C and a part of the third conductor portion 13C overlap. A connecting conductor 15 is arranged in the overlapping portion.

[0040] <Angle> The first coil conductor 11 and the second coil conductor 13 each have a different angle at both ends in the width direction in a cross section perpendicular to the extension direction. A specific description will be given with reference to Fig. 3 and Fig. 4. Fig. 3 and Fig. 4 show an example of a cross section of the first conductor portion 11A of the first coil conductor 11. The angles will be described below using the first conductor portion 11A as an example.

[0041] 3 and 4 show a cross section perpendicular to the extension direction (first direction D1) of the first conductor portion 11A. The perpendicular cross section of the first conductor portion 11A is a cross section along the third direction D3. The thickness direction of the first conductor portion 11A is the second direction D2. The width direction of the first conductor portion 11A is the third direction D3. The perpendicular cross section of the second conductor portion 11B is a cross section along the first direction D1. The perpendicular cross section of the third conductor portion 11C is a cross section along the third direction D3.

[0042] As shown in Fig. 4, the first conductor 11A has a first surface 11Aa and a second surface 11Ab. The first surface 11Aa is a surface on the main surface 3c side. The second surface 11Ab is a surface on the main surface 3d side. In this embodiment, the first surface 11Aa and the second surface 11Ab are flat surfaces. The first surface 11Aa and the second surface 11Ab face each other in the second direction D2. The distance between the first surface 11Aa and the second surface 11Ab corresponds to the thickness of the first conductor 11A.

[0043] The first conductor portion 11A has a first end portion 11Ac and a second end portion 11Ad. In this embodiment, the first end portion 11Ac and the second end portion 11Ad have different shapes in the third conductor portion 11C. The first end portion 11Ac is an end portion on the side surface 3f side. That is, the first end portion 11Ac is an inner end portion (inner edge portion) of the coil 9. The first end portion 11Ac is configured to include a first end portion face 11Ae and a second end portion face 11Af. The first end portion face 11Ae is a surface continuous with the first surface 11Aa. The second end portion face 11Af is a surface continuous with the second surface 11Ab. That is, the first surface 11Aa and the second surface 11Ab connect the first end portion 11Ac and the second end portion 11Ad.

[0044] The second end 11Ad is an end on the side of the side surface 3e. In other words, the second end 11Ad is an outer end (outer edge) of the coil 9. The second end 11Ad is configured to include a first end face 11Ag and a second end face 11Ah. The first end face 11Ag is a face continuing to the first face 11Aa. The second end face 11Ah is a face continuing to the second face 11Ab. The first end face 11Ag and the second end face 11Ah are curved. The first end face 11Ag and the second end face 11Ah are curved so that the second end 11Ad gradually (continuously) becomes thinner.

[0045] The angles of the first end 11Ac and the second end 11Ad will be described in detail. As shown in FIG. 4, the first end 11Ac forms a first angle θ1. In this embodiment, the first angle θ1 is an angle formed by a straight line (a straight line connecting the end points) connecting the first point P1 and the second point P2, and a straight line connecting the first point P1 and the third point P3. The first point P1 is the endmost point (closest to the side surface 3f) in the third direction D3 in the first end 11Cc of the third conductor portion 11C. The first point P1 is an intersection point between the first end face 11Ae and the second end face 11Af.

[0046] The second point P2 is a point on the first surface 10Aa, located a distance L1 away from the first point P1 in the third direction D3. The distance L1 is half the thickness T (T / 2) of the first conductor portion 11A (first coil conductor 11). The thickness T is the maximum thickness of the first conductor portion 11A in the second direction D2. The third point P3 is a point on the second surface 10Ab, located a distance L2 away from the first point P1 in the third direction D3. The distance L2 is half the thickness T (T / 2) of the first conductor portion 11A (first coil conductor 11).

[0047] The second end 11Ad forms a second angle θ2. In this embodiment, the second angle θ2 is an angle formed by a straight line (a straight line connecting the end points) connecting the fourth point P4 and the fifth point P5 and a straight line connecting the fourth point P4 and the sixth point P6. The fourth point P4 is the endmost point (closest to the side surface 3e) in the third direction D3 at the second end 11Cd of the first conductor 11A. The distance between the first point P1 and the fourth point P4 is the length L3 in the width direction (third direction D3) of the third conductor 11C.

[0048] The fifth point P5 is a point on the surface 10Ag, which is a distance L4 away from the fourth point P4 in the third direction D3. The distance L4 is half the thickness T (T / 2) of the first conductor portion 11A (first coil conductor 11). The sixth point P6 is a point on the surface 10Ah, which is a distance L5 away from the fourth point P4 in the third direction D3. The distance L5 is half the thickness T (T / 2) of the first conductor portion 11A (first coil conductor 11).

[0049] In the first conductor portion 11A, the first angle θ1 and the second angle θ2 are different. In this embodiment, the first angle θ1 is larger than the second angle θ2 (θ1>θ2). In other words, the second angle θ2 is smaller than the first angle θ1 (θ2<θ1). The first angle θ1 is, for example, 60° or more. The second angle θ2 is, for example, less than 60°.

[0050] Similar to the first conductor portion 11A, the first angle θ1 and the second angle θ2 are set in the second conductor portion 11B and the third conductor portion 11C of the first coil conductor 11. Similarly to the first conductor portion 11A, the first angle θ1 and the second angle θ2 are set in the first conductor portion 13A, the second conductor portion 13B and the third conductor portion 13C of the second coil conductor 13.

[0051] <Taper rate> The first coil conductor 11 and the second coil conductor 13 each have a different taper rate at both ends in the width direction in a cross section perpendicular to the extending direction. A specific description will be given with reference to Fig. 5. Fig. 5 illustrates a cross section of the first conductor portion 11A of the first coil conductor 11. The taper rate will be described below using the first conductor portion 11A as an example.

[0052] The taper ratios of the first end 11Ac and the second end 11Ad will be described in detail. The first end 11Ac has a first taper ratio TR1. In this embodiment, the first taper ratio TR1 is calculated based on the ratio between the thickness T of the first conductor portion 11A and the distance L6. The distance L6 is the distance (first distance) in the third direction D3 between the position at which the thickness of the first end 11Ac is T / 2 and the first point P1. The first taper ratio TR1 (%) is calculated by the following formula. First taper ratio TR1 = (T / L6) x 100 That is, the first taper ratio TR1 is calculated by dividing the thickness T of the first conductor 11A by the distance L6 and multiplying the result by 100.

[0053] The second end 11Ad has a second taper ratio TR2. In this embodiment, the second taper ratio TR2 is calculated based on the ratio of the thickness T of the first conductor 11A to the distance L7. The distance L7 is the distance (second distance) in the third direction D3 between the position at the second end 11Ad where the thickness is T / 2 and the fourth point P4. The second taper ratio TR2 (%) is calculated by the following formula. Second taper rate TR2(%)=(T / L7)×100 That is, the second taper ratio TR2 is calculated by dividing the thickness T of the first conductors 11A by the distance L7 and multiplying the result by 100.

[0054] In the first conductor portion 11A, the first taper ratio TR1 and the second taper ratio TR2 are different. In the present embodiment, the first taper ratio TR1 is larger than the second taper ratio TR2 (TR1 > TR2). In other words, the second taper ratio TR2 is smaller than the first taper ratio TR1 (TR2 < TR1). The first taper ratio TR1 is, for example, 55% or more. The second taper ratio TR2 is, for example, less than 55%.

[0055] In the second conductor portion 11B and the third conductor portion 11C of the first coil conductor 11 as well, the first taper ratio TR1 and the second taper ratio TR2 are set in the same manner as in the first conductor portion 11A. Also, in the first conductor portion 13A, the second conductor portion 13B, and the third conductor portion 13C of the second coil conductor 13, the first taper ratio TR1 and the second taper ratio TR2 are set in the same manner as in the first conductor portion 11A.

[0056] In the coil component 1, when current flows through the first coil conductor 11 and the second coil conductor 13, the current distribution at the inner edge portions of the first coil conductor 11 and the second coil conductor 13 is higher than that at the outer edge portions. That is, taking the first conductor portion 11A of the first coil conductor 11 as an example, the current distribution at the first end portion 11Ac is higher than that at the second end portion 11Ad. It can be said that there is an offset in the current distribution in the first coil conductor 11. In the first conductor portion 11A, the electric field strength at the first end portion 11Ac is higher than that at the second end portion 11Ad.

[0057] As described above, in the coil component 1 according to this embodiment, the first coil conductor 11 and the second coil conductor 13 have different angles at both ends in the width direction in a cross section perpendicular to the extending direction. The first coil conductor 11 and the second coil conductor 13 have a first end and a second end. The first end forms a first angle θ1, and the second end forms a second angle θ2. The first coil conductor 11 and the second coil conductor 13 have different first and second angles θ1 and θ2. In this embodiment, the first angle θ1 is larger than the second angle θ2 (θ1>θ2). The first end has a first taper rate TR1, and the second end has a second taper rate TR2. The first coil conductor 11 and the second coil conductor 13 have different first and second taper rates TR1 and TR2. In this embodiment, the first taper rate TR1 is larger than the second taper rate TR2 (TR1>TR2). With this configuration, a high Q value can be obtained at the first end.

[0058] In the coil component 1 according to this embodiment, a part of the first coil conductor 11 and a part of the second coil conductor 13 overlap with each other. In this configuration, by making the second angle θ2 of the second end smaller than the first angle θ1 of the first end, the distance (the distance in the second direction D2) between the second end of the first coil conductor 11 and the second end of the second coil conductor 13 can be increased, thereby reducing the stray capacitance between the first coil conductor 11 and the second coil conductor 13. This allows the coil component 1 to have a higher self-resonant frequency.

[0059] In the coil component 1 according to this embodiment, the first angle θ1 is 60° or more. The second angle θ2 is less than 60°. The first taper ratio TR1 is 55% or more.

The angles will be described below using the first coil conductor 27A and the first coil conductor 29A as examples.

[0073] Fig. 10 shows a cross section perpendicular to the extension direction (third direction D3) of the first coil conductor 27A and the first coil conductor 29A. The perpendicular cross section of the first coil conductor 27A and the first coil conductor 29A is a cross section along the first direction D1. In the example shown in Fig. 10, the thickness direction of the first coil conductor 27A and the first coil conductor 29A is the second direction D2. The width direction of the first coil conductor 27A and the first coil conductor 29A is the first direction D1.

[0082] In the first coil conductor 29A, the first angle θ5 and the second angle θ6 are different. In the present embodiment, the first angle θ5 is larger than the second angle θ6 (θ5 > θ6). In other words, the second angle θ6 is smaller than the first angle θ5 (θ6 < θ5). The first angle θ5 is, for example, 60° or more. The second angle θ6 is, for example, less than 60°.

[0083] Also in the second coil conductor 29B, the third coil conductor 29C, the fourth coil conductor 29D, the fifth coil conductor 29E, and the sixth coil conductor 29F of the second coil 29, the first angle θ5 and the second angle θ6 are set in the same manner as in the first coil conductor 29A.

In the present embodiment, the first taper ratio TR3 is larger than the second taper ratio TR4 (TR3 > TR4). In other words, the second taper ratio TR4 is smaller than the first taper ratio TR3 (TR4 < TR3). The first taper ratio TR3 is, for example, 55% or more. The second taper ratio TR4 is, for example, less than 55%.

[0086] Also in the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F of the first coil 27, the first taper ratio TR3 and the second taper ratio TR4 are set in the same manner as in the first coil conductor 27A.

[0090] The second end portion 27Ad of the first coil conductor 27A and the second end portion 29Ad of the first coil conductor 29A are arranged to face (adjacent to) each other in the first direction D1. The first angle θ3 of the first end portion 27Ac of the first coil conductor 27A and the first angle θ5 of the first end portion 29Ac of the first coil conductor 29A may be the same or different. The second angle θ4 of the second end portion 27Ad of the first coil conductor 27A and the second angle θ6 of the second end portion 29Ad of the first coil conductor 29A may be the same or different.

[0091] In the coil component 1A, when a current is applied, the current distribution is higher at the inner edge portions of the first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F of the first coil 27 than at the outer edge portions. In other words, taking the first coil conductor 27A as an example, the current distribution is higher at the first end portion 27Ac than at the second end portion 27Ad. It can also be said that the current distribution is biased in the first coil conductor 27A. In the first coil conductor 27A, the electric field intensity is higher at the first end portion 27Ac than at the second end portion 27Ad.

[0092] In addition, in the coil component 1A, when a current is applied, the current distribution is higher at the inner edge portions of the first coil conductor 29A, the second coil conductor 29B, the third coil conductor 29C, the fourth coil conductor 29D, the fifth coil conductor 29E, and the sixth coil conductor 29F of the second coil 29 than at the outer edge portions. In other words, taking the first coil conductor 29A as an example, the current distribution is higher at the first end portion 29Ac than at the second end portion 29Ad. It can also be said that the current distribution is biased in the first coil conductor 29A. In the first coil conductor 29A, the electric field intensity is higher at the first end portion 29Ac than at the second end portion 29Ad.

[0093] As described above, in the coil component 1A according to this embodiment, the first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F constituting the first coil 27 have different angles at both ends in the width direction in a cross section perpendicular to the extending direction. The first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F have a first end and a second end. The first end forms a first angle θ3, and the second end forms a second angle θ4. The first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F have different first and second angles θ3 and θ4. In this embodiment, the first angle θ3 is larger than the second angle θ4 (θ3>θ4). Moreover, the first end has a first taper rate TR3, and the second end has a second taper rate TR4. The first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F have different first taper rates TR3 and TR4. In this embodiment, the first taper rate TR3 is greater than the second taper rate TR4 (TR3>TR4). In this configuration, the first coil 27 can obtain a high Q value at the first end. Similarly, the second coil 29 can obtain a high Q value.

[0094] In the coil component 1A according to this embodiment, the first coil conductor 27A, the second coil conductor 27B, the third coil conductor 27C, the fourth coil conductor 27D, the fifth coil conductor 27E, and the sixth coil conductor 27F of the first coil 27 overlap with each other. In this configuration, the second angle θ4 of the second end portion is made smaller than the first angle θ3 of the first end portion, so that the distance between the second ends of the coil conductors adjacent to each other in the second direction D2 (the interval in the second direction D2) can be increased, and the stray capacitance between the adjacent coil conductors can be reduced. The stray capacitance of the second coil 29 can also be reduced in the same manner. As a result, the self-resonant frequency of the coil component 1A can be increased.

[0095] In addition, in coil component 1A, the coil conductor of first coil 27 and the coil conductor of second coil 29 are arranged so that their second ends face each other. This reduces stray capacitance between adjacent coil conductors. Also, it is possible to suppress magnetic coupling between adjacent coil conductors. This allows coil component 1A to achieve a higher self-resonant frequency.

[0096] [Third embodiment] Next, a third embodiment will be described. Fig. 11 is a perspective view of an electronic component according to the third embodiment. As shown in Fig. 11, electronic component 1B includes an element body 3, a first external electrode 5 and a second external electrode 7 disposed at both ends of the element body 3, respectively, and a strip line (conductor) 40. Electronic component 1B is a strip line type filter.

[0097] The stripline 40 extends along a first direction D1. One end of the stripline 40 is exposed at an end face 3a of the element body 3 and is connected to the first external electrode 5 (first electrode portion). The other end of the stripline 40 is exposed at an end face 3b of the element body 3 and is connected to the second external electrode 7 (first electrode portion).

[0098] <Angle> In a cross section perpendicular to the extension direction of the stripline 40, the angles of both ends in the width direction are different. FIG. 12 is a diagram showing the cross-sectional configuration of the stripline. FIG. 12 shows a cross section perpendicular to the extension direction (first direction D1) of the stripline 40. The perpendicular cross section of the stripline 40 is a cross section along a third direction D3. In this embodiment, the cross section of the stripline 40 has a trapezoidal shape. The thickness direction of the stripline 40 is the second direction D2. The width direction of the stripline 40 is the third direction D3.

[0099] The stripline 40 has a first surface 40A and a second surface 40B. The first surface 40A is the surface on the main surface 3c side. The second surface 40B is the surface on the main surface 3d side. The distance between the first surface 40A and the second surface 40B corresponds to the thickness of the stripline 40.

[0100] The first conductor portion 11A has a first end portion 40C and a second end portion 40D. In the present embodiment, the first end portion 40C is the end portion on the side surface 3f side. The second end portion 40D is the end portion on the side surface 3e side.

[0101] The angles of the first end portion 40C and the second end portion 40D will be described in detail. The first end portion 40C forms a first angle θ7. The second end portion 40D forms a second angle θ8.

[0102] In the stripline 40, the first angle θ7 and the second angle θ8 are different. In the present embodiment, the first angle θ7 is larger than the second angle θ8 (θ7>θ8). In other words, the second angle θ8 is smaller than the first angle θ7 (θ8<θ7). The first angle θ7 is, for example, 60° or more. The second angle θ8 is, for example, less than 60°.

[0103] <Taper ratio> In the cross section orthogonal to the extending direction of the stripline 40, the taper ratios at both end portions in the width direction are different. The first end portion 40C has a first taper ratio TR7. The second end portion 40D has a second taper ratio TR8. The first taper ratio TR7 and the second taper ratio TR8 can be obtained in the same manner as in the first embodiment.

[0104] In the stripline 40, the first taper ratio TR7 and the second taper ratio TR8 are different. In the present embodiment, the first taper ratio TR7 is larger than the second taper ratio TR8 (TR7>TR8). In other words, the second taper ratio TR8 is smaller than the first taper ratio TR7 (TR8<TR7). The first taper ratio TR7 is, for example, 55% or more. The second taper ratio TR8 is, for example, less than 55%.

[0105] As described above, in the electronic component 1B according to the present embodiment, in a cross section orthogonal to the extending direction, the angles at both ends in the width direction of the strip line 40 are different. The strip line 40 has a first end 40C and a second end 40D. The first end 40C forms a first angle θ7, and the second end 40D forms a second angle θ8. In the strip line 40, the first angle θ7 and the second angle θ8 are different. In the electronic component 1B, the first angle θ7 is larger than the second angle θ8. Also, the first end 40C has a first taper ratio TR7, and the second end 40D has a second taper ratio TR8. In the strip line 40, the first taper ratio TR7 and the second taper ratio TR8 are different. In the present embodiment, the first taper ratio TR7 is larger than the second taper ratio TR8 (TR7>TR8). With this configuration, a high Q value can be obtained at the first end 40C.

[0106] In the electronic component 1B according to the present embodiment, the second angle θ8 of the second end 40D is smaller than the first angle θ7 of the first end 40C (θ8<θ7). Also, the second taper ratio TR8 of the second end 40D is smaller than the first taper ratio TR7 of the first end 40C (TR8<TR7). With this configuration, the distance to other components (such as external electrodes) can be increased, so the parasitic capacitance between the strip line 40 and other components can be reduced. Thereby, in the electronic component 1B, the self-resonant frequency can be increased.
