Technical Field

[0001] The present disclosure relates to an electronic component. Background Art

[0002] Patent document 1 (Japanese Patent Publication No. 7-22241) discloses an electronic component (inductor), which includes: a first magnetic substrate as an insulator, which is formed with a coil groove in a coil pattern of a predetermined shape, a conductor film is formed in the coil groove, the surface is flattened, and a conductor is formed only in the coil groove; and a second magnetic substrate as an insulator, which is bonded and fixed in a manner covering the conductor of the first magnetic substrate. In the electronic component described in Patent document 1, the cross section of the conductor is triangular or trapezoidal. Summary of the invention

[0003] An object of one embodiment of the present disclosure is to provide an electronic component that achieves a high Q value and a higher self-resonant frequency.

[0004] (1) An electronic component according to one embodiment of the present disclosure includes a body and a conductor arranged in the body, wherein the conductor has a first end and a second end in a width direction when viewed from an extension direction of the conductor in a cross section perpendicular to the extension direction of the conductor, the first end forming a first angle, the second end forming a second angle, and the first angle and the second angle are different.

[0005] In an electronic component of one embodiment of the present disclosure, a first angle and a second angle are formed at a first end and a second end of a conductor, respectively, and the first angle is different from the second angle. In this structure, a high Q value can be obtained, for example, by increasing one of the first angle and the second angle. In addition, in the electronic component, for example, by reducing the other of the first angle and the second angle, the stray capacitance between the conductor and other components can be reduced. Thus, in the electronic component, a high frequency of the self-resonant frequency is achieved.

[0006] (2) In the electronic component of (1) above, the first angle may be larger than the second angle. In this structure, a high Q value can be obtained.

[0007] (3) In the electronic component of (2) above, the first angle may be equal to or greater than 60°. In this structure, a high Q value can be obtained.

[0008] (4) In the electronic component of (2) above, the second angle may be smaller than 60°. In this structure, the stray capacitance between the conductor and other components can be reduced. Thus, in the electronic component, a higher self-resonance frequency can be achieved.

[0009] (5) In the electronic component of any one of (1) to (4) above, when current flows through the conductor, the current distribution at the first end is higher than the current distribution at the second end. In this structure, a high Q value can be obtained by making the first angle larger than the second angle.

[0010] (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 bent. In this structure, by bending the first surface and / or the second surface, the angle of the (sharp) end can be reduced. Thus, the stray capacitance between the conductor and other components can be reduced. Therefore, in the electronic component, a high frequency of the self-resonant frequency is achieved.

[0011] (7) An electronic component involved in one embodiment of the present disclosure includes a body and a conductor arranged in the body, wherein the conductor has a first end and a second end in the width direction when viewed from the extension direction in a cross section orthogonal to the extension direction of the conductor, the first end having a first taper rate set based on the ratio of the thickness of the conductor to a first distance from the end of the first end to a position that is 1 / 2 of the thickness in the width direction, and the second end having a second taper rate set based on the ratio of the thickness of the conductor to a second distance from the end of the second end to a position that is 1 / 2 of the thickness in the width direction, and the first taper rate is different from the second taper rate.

[0012] In an electronic component of one embodiment of the present disclosure, a first taper rate and a second taper rate are provided at a first end and a second end of a conductor, respectively, and the first taper rate is different from the second taper rate. In this structure, a high Q value can be obtained by, for example, increasing one of the first taper rate and the second taper rate. In addition, in the electronic component, for example, by reducing the other of the first taper rate and the second taper rate, the stray capacitance between the conductor and other components can be reduced. Thus, in the electronic component, a high frequency of the self-resonant frequency is achieved.

[0013] (8) In the electronic component of (7) above, the first taper ratio may be larger than the second taper ratio. In this structure, a high Q value can be obtained.

[0014] (9) In the electronic component of (8) above, the first taper ratio may be 55% or more. In this structure, a high Q value can be obtained.

[0015] (10) In the electronic component of (8) above, the second taper ratio may be less than 55%. In this structure, the stray capacitance between the conductor and other components can be reduced. Thus, in the electronic component, a higher self-resonance frequency can be achieved.

[0016] (11) In the electronic component of any one of (7) to (10) above, when current flows through the conductor, the current distribution at the first end is higher than the current distribution at the second end. In this structure, a high Q value can be obtained by making the first taper ratio larger than the second taper ratio.

[0017] According to one embodiment of the present disclosure, a high Q value is obtained and a higher self-resonant frequency is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and repeated descriptions are omitted.

[0031] [First embodiment]

[0032] like Figure 1 As shown, the coil component (electronic component) 1 of the first embodiment includes an element body 3 , a first external electrode 5 and a second external electrode 7 respectively arranged at both ends of the element body 3 , and a coil 9 .

[0033] The element body 3 is in the shape of a cuboid. The cuboid shape includes the shape of a cuboid whose corners and edges are chamfered, and the shape of a cuboid whose corners and edges are rounded. The element body 3 has a pair of end faces 3a and 3b opposite to each other, a pair of main faces 3c and 3d opposite to each other, and a pair of side faces 3e and 3f opposite to each other as its outer surface. The relative direction of the pair of end faces 3a and 3b is the first direction D1. The relative direction of the pair of main faces 3c and 3d is the second direction D2. The relative direction of the pair of side faces 3e and 3f is the third direction D3.

[0034] In this embodiment, the first direction D1 is the long side direction of the element body 3. The second direction D2 is the height direction of the element body 3 and is orthogonal to the second direction D2. The third direction D3 is the width direction of the element body 3 and is orthogonal to the second direction D2 and the first direction D1.

[0035] A pair of end faces 3a, 3b extend along the second direction D2 in a manner connecting a pair of main faces 3c, 3d. A pair of end faces 3a, 3b also extend along the third direction D3 (the short side direction of a pair of main faces 3c, 3d). A pair of side faces 3e, 3f extend along the second direction D2 in a manner connecting a pair of main faces 3c, 3d. A pair of side faces 3e, 3f also extend along the first direction D1 (the long side direction of a pair of end faces 3a, 3b). The main surface 3d can be defined as a mounting surface opposite to other electronic devices when the coil component 1 is mounted on other electronic devices (for example, a circuit substrate or an electronic component, etc.).

[0036] The element body 3 is formed by stacking a plurality of dielectric layers (not shown). Each dielectric layer is stacked along the second direction D2. That is, the second direction D2 is the stacking direction. The element body 3 has a plurality of stacked dielectric layers. Each dielectric layer is, for example, made of a dielectric material (BaTiO 3 Ba(Ti,Zr)O 3 system, or (Ba,Ca)TiO 3 In the actual element body 3, a plurality of dielectric layers are integrated to such an extent that the boundaries between the layers cannot be recognized.

[0037] like Figure 1 As shown, the first external electrode 5 is arranged on the end face 3a side of the element body 3, and the second external electrode 7 is arranged on the end face 3b side of the element body 3. That is, the first external electrode 5 and the second external electrode 7 are located at positions separated from each other in the relative direction (first direction D1) of the pair of end faces 3a and 3b.

[0038] The first external electrode 5 is arranged on the side of one end face 3a. 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 is connected to the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part at the ridgeline of the element body 3, and is electrically connected to each other. The first external electrode 5 is formed on five surfaces, 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 formed integrally.

[0039] The second external electrode 7 is arranged on the other end face 3b side. The second external electrode 7 includes five electrode parts, namely, 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 is connected to the second electrode part, the third electrode part, the fourth electrode part, and the fifth electrode part at the ridgeline of the element body 3, and is electrically connected to each other. The second external electrode 7 is formed on five surfaces, 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 formed integrally.

[0040] The first external electrode 5 and the second external electrode 7 include a conductive material (for example, Ag or Pd, etc.). The first external electrode 5 and the second external electrode 7 are formed as a sintered body of a conductive paste containing a conductive material (for example, Ag powder or Pd powder, etc.). A plating layer may also be formed on the surface of the first external electrode 5 and the second external electrode 7. The plating layer is formed, for example, by 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.

[0041] like Figure 2As shown, the coil 9 is formed 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 connecting conductor 15. The first coil conductor 11 forms one end of the coil 9. The first coil conductor 11 is exposed at the end surface 3a of the element body 3 and is connected to the first external electrode 5 (first electrode portion). The second coil conductor 13 forms the other end of the coil 9. The second coil conductor 13 is exposed at the end surface 3b of the element body 3 and is connected to the second external electrode 7 (first electrode portion).

[0042] The first coil conductor 11, the second coil conductor 13 and the connecting conductor 15 are made of a conductive material (for example, Ag, Ni, Cu, etc.) commonly used as a conductor of a coil. 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 conductive material.

[0043] The first coil conductor 11 includes 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 formed (molded) as one body.

[0044] 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. The end portion of the first conductor portion 11A on the side of the end face 3b is connected to the end portion of the second conductor portion 11B on the side of the side face 3e. The end portion of the second conductor portion 11B on the side of the side face 3f is connected to the end portion of the third conductor portion 11C on the side of the end face 3b. In the present embodiment, the length of the first conductor portion 11A is longer than the length of each 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.

[0045] The connection portion 11D is connected to the end portion of the first conductor portion 11A on the end surface 3a side. A portion 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). Thus, the first coil conductor 11 and the first external electrode 5 are electrically connected.

[0046] The second coil conductor 13 includes 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 formed (molded) as one body.

[0047] 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. The end portion of the first conductor portion 13A on the side of the end face 3a is connected to the end portion of the second conductor portion 13B on the side of the side face 3e. The end portion of the second conductor portion 13B on the side of the side face 3f is connected to the end portion of the third conductor portion 13C on the side of the end face 3a. In the present embodiment, the length of the first conductor portion 13A is longer than the length of each 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.

[0048] The connection portion 13D is connected to the end portion of the first conductor portion 13A on the end surface 3b side. A portion of the connection portion 13D is exposed at the end surface 3b. The connection portion 13D is connected to the second external electrode 7 (first electrode portion). Thus, the second coil conductor 13 is electrically connected to the second external electrode 7.

[0049] The connection 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 connection conductor 15 is disposed between the end portion of the third conductor portion 11C on the end face 3a side and the end portion of the third conductor portion 13C on the end face 3b side. The connection conductor 15 is, for example, a through-hole conductor.

[0050] 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 opposite to 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 portion (end portion) of the third conductor portion 11C of the first coil conductor 11 and a portion (end portion) of the third conductor portion 13C of the second coil conductor 13 are arranged opposite to each other in the second direction D2. That is, a portion of the third conductor portion 11C and a portion of the third conductor portion 13C overlap when viewed from the second direction D2. The connection conductor 15 is arranged in the overlapping portion.

[0051] <Angle>

[0052] 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. Figure 3 and Figure 4 Provide explanation. Figure 3 and Figure 4 The cross section of the first conductor portion 11A of the first coil conductor 11 is illustrated. Hereinafter, the angle will be described using the first conductor portion 11A as an example.

[0053] exist Figure 3 and Figure 4, a cross section orthogonal to the extension direction (first direction D1) of the first conductor portion 11A is shown. The cross section orthogonal to 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. In addition, the cross section orthogonal to the second conductor portion 11B is a cross section along the first direction D1. The cross section orthogonal to the third conductor portion 11C is a cross section along the third direction D3.

[0054] like Figure 4 As shown, the first conductor portion 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 are opposite to each other in the second direction D2. The distance between the first surface 11Aa and the second surface 11Ab is equivalent to the thickness of the first conductor portion 11A.

[0055] The first conductor portion 11A has a first end portion 11Ac and a second end portion 11Ad. In the present embodiment, in the third conductor portion 11C, the shapes of the first end portion 11Ac and the second end portion 11Ad are different. The first end portion 11Ac is an end portion on the side of the side surface 3f. That is, the first end portion 11Ac is an end portion (inner edge portion) on the inner side of the coil 9. The first end portion 11Ac is composed of a first end surface 11Ae and a second end surface 11Af. The first end surface 11Ae is a surface continuous with the first surface 11Aa. The second end surface 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.

[0056] The second end portion 11Ad is an end portion on the side of the side surface 3e. That is, the second end portion 11Ad is an end portion (outer edge portion) on the outside of the coil 9. The second end portion 11Ad is composed of a first end surface 11Ag and a second end surface 11Ah. The first end surface 11Ag is a surface continuous with the first surface 11Aa. The second end surface 11Ah is a surface continuous with the second surface 11Ab. The first end surface 11Ag and the second end surface 11Ah are bent. The first end surface 11Ag and the second end surface 11Ah are bent in a manner that the second end portion 11Ad gradually (continuously) becomes thinner.

[0057] The angles of the first end portion 11Ac and the second end portion 11Ad are described in detail. Figure 4As shown, the first end portion 11Ac forms a first angle θ1. In the present embodiment, the first angle θ1 is an angle formed by a straight line connecting the first point P1 and the second point P2 (a straight line connecting the end points) and a straight line connecting the first point P1 and the third point P3. The first point P1 is a point closest to the end (closest to the side surface 3f) in the third direction D3 in the first end portion 11Cc of the third conductor portion 11C. The first point P1 is an intersection point of the first end surface 11Ae and the second end surface 11Af.

[0058] The second point P2 is a point on the first surface 10Aa that is away from the first point P1 by a distance L1 in the third direction D3. The distance L1 is a distance (T / 2) that is 1 / 2 of the thickness T 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 that is away from the first point P1 by a distance L2 in the third direction D3. The distance L2 is a distance (T / 2) that is 1 / 2 of the thickness T of the first conductor portion 11A (first coil conductor 11).

[0059] The second end portion 11Ad forms a second angle θ2. In the present embodiment, the second angle θ2 is an angle formed by a straight line connecting the fourth point P4 and the fifth point P5 (a straight line connecting the end points) and a straight line connecting the fourth point P4 and the sixth point P6. The fourth point P4 is a point closest to the end portion (closest to the side surface 3e) in the third direction D3 in the second end portion 11Cd of the first conductor portion 11A. The distance between the first point P1 and the fourth point P4 is a length L3 in the width direction (third direction D3) of the third conductor portion 11C.

[0060] The fifth point P5 is a point on the plane 10Ag that is away from the fourth point P4 by a distance L4 in the third direction D3. The distance L4 is a distance (T / 2) of 1 / 2 of the thickness T of the first conductor portion 11A (first coil conductor 11). The sixth point P6 is a point on the plane 10Ah that is away from the fourth point P4 by a distance L5 in the third direction D3. The distance L5 is a distance (T / 2) of 1 / 2 of the thickness T of the first conductor portion 11A (first coil conductor 11).

[0061] In the first conductor portion 11A, the first angle θ1 and the second angle θ2 are different. In the present embodiment, the first angle θ1 is greater than the second angle θ2 (θ1>θ2). In other words, the second angle θ2 is less than the first angle θ1 (θ2<θ1). The first angle θ1 is, for example, greater than 60°. The second angle θ2 is, for example, less than 60°.

[0062] 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 in the same manner as the first conductor portion 11A. In addition, the first conductor portion 13A, the second conductor portion 13B, and the third conductor portion 13C of the second coil conductor 13 in the same manner as the first conductor portion 11A.

[0063] <Taper rate>

[0064] The first coil conductor 11 and the second coil conductor 13 have different taper rates at both ends in the width direction in a cross section perpendicular to the extending direction. Figure 5 Provide explanation. Figure 5 The cross section of the first conductor portion 11A of the first coil conductor 11 is illustrated. Hereinafter, the taper rate will be described using the first conductor portion 11A as an example.

[0065] The taper ratios of the first end portion 11Ac and the second end portion 11Ad are described in detail. The first end portion 11Ac has a first taper ratio TR1. In the present embodiment, the first taper ratio TR1 is obtained based on the ratio of the thickness T of the first conductor portion 11A to the distance L7. The distance L7 is the distance (first distance) in the third direction D3 between the position where the thickness of the first end portion 11Ac becomes T / 2 and the first point P1. The first taper ratio TR1 (%) is obtained by the following formula.

[0066] First taper ratio TR1 = (T / L7) × 100

[0067] That is, the first taper ratio TR1 is calculated by multiplying 100 the value obtained by dividing the thickness T of the first conductor portion 11A by the distance L7 .

[0068] The second end portion 11Ad has a second taper ratio TR2. In the present embodiment, the second taper ratio TR2 is obtained based on the ratio of the thickness T of the first conductor portion 11A to the distance L6. The distance L6 is the distance (second distance) in the third direction D3 between the position where the thickness of the second end portion 11Ad becomes T / 2 and the fourth point P4. The second taper ratio TR2 (%) is obtained by the following formula.

[0069] Second taper ratio TR2 (%) = (T / L6) × 100

[0070] That is, the second taper ratio TR2 is calculated by multiplying 100 the value obtained by dividing the thickness T of the first conductor portion 11A by the distance L6 .

[0071] In the first conductor portion 11A, the first taper rate TR1 and the second taper rate TR2 are different. In the present embodiment, the first taper rate TR1 is greater than the second taper rate TR2 (TR1>TR2). In other words, the second taper rate TR2 is less than the first taper rate TR1 (TR2<TR1). The first taper rate TR1 is, for example, 55% or more. The second taper rate TR2 is, for example, less than 55%.

[0072] The first conductor portion 11B and the third conductor portion 11C of the first coil conductor 11 also have the first taper rate TR1 and the second taper rate TR2 set similarly to the first conductor portion 11A. In addition, the first conductor portion 13A, the second conductor portion 13B, and the third conductor portion 13C of the second coil conductor 13 also have the first taper rate TR1 and the second taper rate TR2 set similarly to the first conductor portion 11A.

[0073] In the coil component 1, when current flows through the first coil conductor 11 and the second coil conductor 13, the current distribution of the inner edge of the first coil conductor 11 and the second coil conductor 13 becomes higher than the current distribution of the outer edge. That is, when the first conductor portion 11A of the first coil conductor 11 is used as an example, the current distribution of the first end portion 11Ac becomes higher than the current distribution of the second end portion 11Ad. In the first coil conductor 11, it can also be said that a deviation occurs in the current distribution. In the first conductor portion 11A, the electric field strength of the first end portion 11Ac becomes higher than the electric field strength of the second end portion 11Ad.

[0074] As described above, in the coil component 1 of the present embodiment, the first coil conductor 11 and the second coil conductor 13 have different angles at both ends in the width direction in the cross section orthogonal to the extension direction. The first coil conductor 11 and the second coil conductor 13 have a first end and a second end. The first end constitutes a first angle θ1, and the second end constitutes a second angle θ2. In the first coil conductor 11 and the second coil conductor 13, the first angle θ1 and the second angle θ2 are different. In the present embodiment, the first angle θ1 is greater than the second angle θ2 (θ1>θ2). In addition, the first end has a first taper rate TR1, and the second end has a second taper rate TR2. In the first coil conductor 11 and the second coil conductor 13, the first taper rate TR1 and the second taper rate TR2 are different. In the present embodiment, the first taper rate TR1 is greater than the second taper rate TR2 (TR1>TR2). In this structure, a high Q value can be obtained at the first end.

[0075] In the coil component 1 of the present embodiment, a portion of the first coil conductor 11 overlaps a portion of the second coil conductor 13. In this structure, by making the second angle θ2 of the second end smaller than the first angle θ1 of the first end, the distance between the second end of the first coil conductor 11 and the second end of the second coil conductor 13 (the interval in the second direction D2) can be extended, and thus the stray capacitance between the first coil conductor 11 and the second coil conductor 13 can be reduced. As a result, in the coil component 1, a high frequency of the self-resonant frequency is achieved.

[0076] In the coil component 1 of the present embodiment, the first angle θ1 is greater than 60°. The second angle θ2 is less than 60°. In addition, the first taper rate TR1 is greater than 55%. The second taper rate TR2 is less than 55%. In these structures, a high Q value is obtained in the first coil conductor 11 and the second coil conductor 13, and a high frequency of the self-resonant frequency is achieved.

That is, when the first coil conductor 27A is used as an example, the current distribution of the first end 27Ac becomes higher than the current distribution of the second end 27Ad. In the first coil conductor 27A, it can also be said that a deviation occurs in the current distribution. In the first coil conductor 27A, the electric field strength of the first end 27Ac becomes higher than the electric field strength of the second end 27Ad.

[0112] In addition, in the coil component 1A, when power is applied, the current distribution of the inner edge 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 becomes higher than the current distribution of the outer edge. That is, when the first coil conductor 29A is used as an example, the current distribution of the first end 29Ac becomes higher than the current distribution of the second end 29Ad. In the first coil conductor 29A, it can also be said that a deviation occurs in the current distribution. In the first coil conductor 29A, the electric field strength of the first end 29Ac becomes higher than the electric field strength of the second end 29Ad.

[0113] As described above, in the coil component 1A of the present 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 the cross section orthogonal to the extension 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. In 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, the first angle θ3 and the second angle θ4 are different. In the present embodiment, the first angle θ3 is greater than the second angle θ4 (θ3>θ4). In addition, the first end has a first taper rate TR3, and the second end has a second taper rate TR4. In 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, the first taper rate TR3 and the second taper rate TR4 are different. In the present embodiment, the first taper rate TR3 is greater than the second taper rate TR4 (TR3>TR4). In this structure, in the first coil 27, a high Q value can be obtained at the first end. The second coil 29 can also obtain a high Q value.

[0114] In the coil component 1A of the present embodiment, in 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, adjacent coil conductors overlap. In this structure, by making the second angle θ4 of the second end smaller than the first angle θ3 of the first end, the distance between the second ends of the adjacent coil conductors in the second direction D2 (the interval between the second direction D2) can be extended, and thus, the stray capacitance between the adjacent coil conductors can be reduced. The second coil 29 also achieves a reduction in stray capacitance. Thus, in the coil component 1A, a high frequency of the self-resonant frequency is achieved.

[0115] In addition, in the coil component 1A, the coil conductor of the first coil 27 and the coil conductor of the second coil 29 are arranged so that the second ends are opposite to each other. Thus, the stray capacitance is reduced in the adjacent coil conductors. In addition, the magnetic coupling can be suppressed in the adjacent coil conductors. Thus, in the coil component 1A, the self-resonant frequency is increased in a high frequency.

[0116] [Third Embodiment]

[0117] Next, a third embodiment will be described. Fig.11 is a perspective view of an electronic component according to a third embodiment.

[0120] In the strip line 40 , in a cross section perpendicular to the extending direction, both ends in the width direction have different angles. Fig.12 is a diagram showing the cross-sectional structure of a strip line. Fig.12 , a cross section orthogonal to the extension direction (first direction D1) of the strip line 40 is shown. The orthogonal cross section in the strip line 40 is a cross section along the third direction D3. In the present embodiment, the cross section of the strip line 40 is trapezoidal. The thickness direction of the strip line 40 is the second direction D2. The width direction of the strip line 40 is the third direction D3.

[0121] The strip line 40 has a first surface 40A and a second surface 40B. The first surface 40A is a surface on the main surface 3 c side. The second surface 40B is a surface on the main surface 3 d side. The distance between the first surface 40A and the second surface 40B corresponds to the thickness of the strip line 40 .

[0123] 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, and the second end portion 40D forms a second angle θ8.

[0124] In the strip line 40, the first angle θ7 and the second angle θ8 are different. In the present embodiment, the first angle θ7 is greater than the second angle θ8 (θ7>θ8). In other words, the second angle θ8 is less than the first angle θ7 (θ8<θ7). The first angle θ7 is, for example, greater than 60°. The second angle θ8 is, for example, less than 60°.

[0125] <Taper rate>

[0126] The strip line 40 has different taper rates at both ends in the width direction in a cross section perpendicular to the extending direction. The first end 40C has a first taper rate TR7. The second end 40D has a second taper rate TR8. The first taper rate TR7 and the second taper rate TR8 can be obtained in the same manner as in the first embodiment.

[0127] In the strip line 40, the first taper rate TR7 and the second taper rate TR8 are different. In the present embodiment, the first taper rate TR7 is greater than the second taper rate TR8 (TR7>TR8). In other words, the second taper rate TR8 is less than the first taper rate TR7 (TR8<TR7). The first taper rate TR7 is, for example, 55% or more. The second taper rate TR8 is, for example, less than 55%.

[0128] As described above, in the electronic component 1B of the present embodiment, the strip line 40 has different angles at both ends in the width direction in a cross section orthogonal to the extension direction. 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 greater than the second angle θ8. In addition, the first end 40C has a first taper rate TR7, and the second end 40D has a second taper rate TR8. In the strip line 40, the first taper rate TR7 and the second taper rate TR8 are different. In the present embodiment, the first taper rate TR7 is greater than the second taper rate TR8 (TR7>TR8). In this structure, a high Q value can be obtained at the first end 40C.

[0129] In the electronic component 1B of the present embodiment, the second angle θ8 of the second end portion 40D is smaller than the first angle θ7 of the first end portion 40C (θ8<θ7). In addition, the second taper rate TR8 of the second end portion 40D is smaller than the first taper rate TR7 of the first end portion 40C (TR8<TR7). In this structure, the distance from other components (external electrodes, etc.) can be extended, so the stray capacitance between the strip line 40 and other components can be reduced. As a result, in the electronic component 1B, a higher frequency of the self-resonant frequency is achieved.

The bonding of the metal magnetic particles is achieved, for example, by bonding of oxide films formed on the surfaces of the metal magnetic particles. In the dielectric layer, the metal magnetic particles are electrically insulated from each other by bonding of the oxide films. The thickness of the oxide film is, for example, 5 to 60 nm or less. The oxide film may also be composed of one or more layers.
