Summary of the Invention

Problems to be Solved by the Invention

[0004] In inductor components, the inductance value (hereinafter referred to as "inductance value") is set by factors such as the length of the conductor constituting the inductor. There are cases where an inductor component with a low inductance value is required as an inductor component. In an inductor component with a low inductance value, adjustment of the inductance value is not easy.

[0005] One aspect of the present disclosure aims to provide an inductor component that allows easy adjustment of the inductance value.

Means for Solving the Problems

[0006] (1) An inductor component relating to one aspect of the present disclosure comprises a base body, a pair of terminal electrodes disposed on the base body, and an inductor disposed within the base body, wherein the inductor has a first conductor extending in one direction and having one end in one direction connected to one terminal electrode, a second conductor extending in one direction and having one end in one direction connected to the other terminal electrode, and a connecting conductor connecting the other end in one direction of the first conductor to the other end in one direction of the second conductor, wherein the cross-sectional area of ​​the cross section perpendicular to at least one direction of the first conductor and the second conductor is greater than the cross-sectional area of ​​the cross section perpendicular to the direction of extension of the connecting conductor.

[0007] In an inductor component relating to one aspect of this disclosure, the cross-sectional area of ​​the section perpendicular to at least one direction of the first conductor and the second conductor is larger than the cross-sectional area of ​​the section perpendicular to the extending direction of the connecting conductor. In this way, the inductance value of the inductor component can be reduced by making the cross-sectional area of ​​at least one of the first conductor and the second conductor larger than the cross-sectional area of ​​the connecting conductor. As a result, the inductor component allows for adjustment of the inductance value by the connecting conductor after reducing the inductance value. Therefore, the inductor component allows for easy adjustment (setting) of the inductance value.

[0008] (2) In the inductor component described in (1) above, multiple inductors are arranged within the element, and the multiple inductors may be electrically connected in parallel. In this configuration, the inductance value of the inductor component can be set by the number of inductors.

[0009] (3) In the inductor component described in (1) or (2) above, the base body may be made of a material that transmits light. In this configuration, the internal structure of the base body can be observed. Therefore, in the inductor component, it is possible to distinguish by visual inspection the surface of the base body other than the mounting surface on which the terminal electrodes are placed, based on the internal structure of the base body.

[0010] (4) In the inductor component described in (3) above, the base body has a mounting surface on which a pair of terminal electrodes are arranged, and a main surface facing the mounting surface in one direction, and the connecting conductor may be positioned on the base body closer to the main surface than the center in one direction. In this configuration, since the connecting conductor is positioned closer to the main surface than the center in one direction, the connecting conductor can be seen from the main surface side when the base body is made of a light-transmitting material. As a result, in the inductor component, it is possible to distinguish the surface of the base body other than the mounting surface on which the terminal electrodes are arranged by sight.

[0011] (5) In any one of the inductor components described in (1) to (4) above, the body has a mounting surface on which a pair of terminal electrodes are arranged, and a main surface facing the mounting surface in one direction, and the pair of terminal electrodes may be arranged only on the mounting surface. The pair of terminal electrodes may be so-called bottom terminals.

[0012] (6) In any one of the inductor components described in (1) to (5) above, the first conductor and the second conductor and the connecting conductor may have the same width. In this configuration, a sudden change in the cross-sectional area between the first conductor and the second conductor and the connecting conductor can be suppressed. This prevents a decrease in the Q value in the inductor component due to a sudden change in the cross-sectional area.

[0013] (7) In any one of the inductor components described in (1) to (6) above, the cross-sectional area of ​​at least one of the first conductor and the second conductor may be 0.02 times or more the cross-sectional area perpendicular to one direction of the terminal electrode. In this configuration, abrupt changes in the cross-sectional area between at least one of the first conductor and the second conductor and the terminal electrode can be suppressed. As a result, the Q value of the inductor component can be suppressed from decreasing due to abrupt changes in the cross-sectional area. [Effects of the Invention]

[Detailed Description of Embodiments]

[0016] 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 redundant descriptions are omitted.

[0017] [First Embodiment] FIG. 1 is a perspective view of an inductor component according to the first embodiment. FIG. 2 is a view of the inductor component shown in FIG. 1 as viewed from one end face side. FIG. 3 is a view of the inductor component shown in FIG. 1 as viewed from one side face side. FIG. 4 is a view of the inductor component shown in FIG. 1 as viewed from one main surface side. As shown in FIG. 1 to FIG. 4, the inductor component 1 includes an element body 2, a first terminal electrode 3, a second terminal electrode 4, and an inductor 5.

[0018] The element body 2 has a rectangular parallelepiped shape. The rectangular parallelepiped shape includes a rectangular parallelepiped shape in which corner portions and ridge portions are chamfered, and a rectangular parallelepiped shape in which corner portions and ridge portions are rounded. The element body 2 has, as outer surfaces, a pair of end faces 2a and 2b, a pair of main surfaces 2c and 2d, and a pair of side faces 2e and 2f. The end faces 2a and 2b face each other. The main surfaces 2c and 2d face each other. The side faces 2e and 2f face each other. Hereinafter, the facing direction of the end faces 2a and 2b is defined as a first direction D1, the facing direction of the main surfaces 2c and 2d is defined as a second direction (one direction) D2, and the facing direction of the side faces 2e and 2f is defined as a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are substantially orthogonal to each other.

[0019] The end faces 2a and 2b extend in the second direction D2 to connect the main faces 2c and 2d. The end faces 2a and 2b also extend in the third direction D3 to connect the side faces 2e and 2f. The main faces 2c and 2d extend in the first direction D1 to connect the end faces 2a and 2b. The main faces 2c and 2d also extend in the third direction D3 to connect the side faces 2e and 2f. The side faces 2e and 2f extend in the first direction D1 to connect the end faces 2a and 2b. The side faces 2e and 2f also extend in the second direction D2 to connect the main faces 2c and 2d.

[0020] The main surface 2d is the mounting surface, and is the surface that faces other electronic equipment (e.g., a circuit board or inductor component) when mounting the inductor component 1 to other electronic equipment (e.g., a circuit board or inductor component) not shown. The end surfaces 2a and 2b are surfaces that are continuous with the mounting surface (i.e., the main surface 2d).

[0021] In the embodiment illustrated in Figure 1, the length of the base body 2 in the first direction D1 is longer than the length of the base body 2 in the second direction D2 and the length of the base body 2 in the third direction D3. The length of the base body 2 in the second direction D2 is shorter than the length of the base body 2 in the third direction D3. That is, in this embodiment, the end faces 2a, 2b, main faces 2c, 2d and side faces 2e, 2f are rectangular in shape. The length of the base body 2 in the second direction D2 may be equal to the length of the base body 2 in the third direction D3, or it may be longer than the length of the base body 2 in the third direction D3.

[0022] In this embodiment, "equivalent" means not only being equal, but also including slight differences or manufacturing tolerances within a predetermined range. For example, if multiple values ​​fall within ±5% of the average of those multiple values, then those multiple values ​​are defined as equivalent.

[0023] Element 2 is formed by stacking multiple elemental layers (insulating layers) in the second direction D2. In other words, the stacking direction of element 2 is the second direction D2. In the actual element 2, the multiple elemental layers may be integrated to the extent that the boundaries between them are not visible, or they may be integrated in such a way that the boundaries between them are visible.

[0024] The base body 2 has visible light transmittance (transparency). The base body 2 has a predetermined light transmittance. The base body 2 is formed of a transparent material. The base layer constituting the base body 2 may be, for example, a resin layer. The material of the base layer includes, for example, at least one selected from liquid crystal polymer, polyimide resin, crystalline polystyrene, epoxy resin, acrylic resin, bismalade resin, and fluororesin. The base layer may contain a filler. The filler may be, for example, an inorganic filler. An example of an inorganic filler is silica (SiO2). The base layer may not contain a filler.

[0025] The base layer may also contain a magnetic material. The magnetic material of the base layer may include, for example, a Ni-Cu-Zn ferrite material, a Ni-Cu-Zn-Mg ferrite material, or a Ni-Cu ferrite material. The magnetic material of the base layer may also contain, for example, an Fe alloy. The base layer may also contain, for example, a non-magnetic material. The non-magnetic material of the base layer may include, for example, a glass ceramic material or a dielectric material.

[0026] The first terminal electrode 3 and the second terminal electrode 4 are each provided on the base body 2. The first terminal electrode 3 and the second terminal electrode 4 are each positioned on the main surface 2d of the base body 2. The first terminal electrode 3 and the second terminal electrode 4 are provided on the base body 2 spaced apart from each other in the first direction D1. Specifically, the first terminal electrode 3 is positioned on the end face 2a side of the base body 2. The second terminal electrode 4 is positioned on the end face 2b side of the base body 2.

[0027] Each of the first terminal electrode 3 and the second terminal electrode 4 may, for example, have a rectangular shape. Each of the first terminal electrode 3 and the second terminal electrode 4 is positioned such that each side is aligned with the first direction D1 or the third direction D3. As shown in Figure 2, the surfaces of each of the first terminal electrode 3 and the second terminal electrode 4 are flush with the main surface 2d. That is, in this embodiment, neither the first terminal electrode 3 nor the second terminal electrode 4 protrudes from the main surface 2d. It can also be said that the first terminal electrode 3 and the second terminal electrode 4 are exposed to the main surface 2d. The first terminal electrode 3 and the second terminal electrode 4 are formed of a conductive material (for example, Cu).

[0028] Each of the first terminal electrode 3 and the second terminal electrode 4 may be provided with a plating layer (not shown) containing, for example, Ni, Sn, or Au, by electroplating or electroless plating. The plating layer may have, for example, a Ni plating film containing Ni that covers the first terminal electrode 3 and the second terminal electrode 4, and an Au plating film containing Au that covers the Ni plating film.

[0029] The inductor 5 is located within the main body 2. The inductor 5 has a first pillar (first conductor) 6, a second pillar (second conductor) 7, and a connecting conductor 8. The inductor 5 is constructed by electrically connecting the first pillar 6, the second pillar 7, and the connecting conductor 8. The inductor axis of the inductor 5 is provided along the third direction D3. The first pillar 6, the second pillar 7, and the connecting conductor 8 are made of a conductive material. In this embodiment, the first pillar 6, the second pillar 7, and the connecting conductor 8 are made of a material mainly composed of Cu. The first pillar 6, the second pillar 7, and the connecting conductor 8 are spaced apart from the end faces 2a, 2b, the main faces 2c, 2d, and the side faces 2e, 2f.

[0030] The first pillar 6 is positioned near the end face 2a of the base body 2 in the first direction D1. The first pillar 6 is positioned in the center in the third direction D3. The first pillar 6 extends along the second direction D2. In this embodiment, the first pillar 6 has a prismatic shape. The cross-sectional shape of the first pillar 6 (cross-sectional shape in the direction perpendicular to the second direction D2) is rectangular. The first pillar 6 can be constructed by stacking multiple pillar materials in the second direction D2. The pillar material is, for example, truncated square pyramidal. One end of the first pillar 6 (the end on the main surface 2d side) is connected to the first terminal electrode 3. The first pillar 6 is connected to the edge on the end face 2a side of the first terminal electrode 3. The other end of the first pillar 6 (the end on the main surface 2c side) is connected to the connecting conductor 8.

[0031] The second pillar 7 is positioned near the end face 2b of the base body 2 in the first direction D1. The second pillar 7 is positioned in the center in the third direction D3. The first pillar 6 and the second pillar 7 are positioned opposite each other in the first direction D1. The second pillar 7 extends along the second direction D2. In this embodiment, the second pillar 7 has a prismatic shape. The cross-sectional shape of the second pillar 7 (cross-sectional shape in the direction perpendicular to the second direction D2) is rectangular. The second pillar 7 can be constructed by stacking multiple pillar materials in the second direction D2. The pillar material is, for example, truncated square pyramidal. One end of the second pillar 7 is connected to the second terminal electrode 4. The second pillar 7 is connected to the edge of the second terminal electrode 4 on the end face 2b side. The other end of the second pillar 7 is connected to the connecting conductor 8.

[0032] The connecting conductor 8 is positioned closer to the main surface 2c of the base body 2. The connecting conductor 8 is positioned closer to the main surface 2c than the center of the second direction D2. The connecting conductor 8 extends along the first direction D1. The connecting conductor 8 connects the first pillar 6 and the second pillar 7. The connecting conductor 8 spans across the first pillar 6 and the second pillar 7. In this embodiment, the connecting conductor 8 has a prismatic shape. The cross-sectional shape of the connecting conductor 8 is rectangular. One end of the connecting conductor 8 in the direction of extension (the end on the end face 2a side) is connected to the other end of the first pillar 6. The other end of the connecting conductor 8 in the direction of extension (the end on the end face 2b side) is connected to the other end of the second pillar 7.

[0033] Figure 5(a) shows a cross-section of the first pillar 6, Figure 5(b) shows a cross-section of the second pillar 7, and Figure 5(c) shows a cross-section of the connecting conductor 8. The cross-sections of the first pillar 6 and the second pillar 7 shown in Figures 5(a) and 5(b) are planes perpendicular to the second direction D2. The cross-section of the connecting conductor 8 shown in Figure 5(c) is a plane perpendicular to the first direction D1.

[0034] In this embodiment, the width W1 of the first pillar 6, the width W2 of the second pillar 7, and the width W3 of the connecting conductor 8 are the same (W1=W2=W3). Widths W1, W2, and W3 are the widths in the third direction D3.

[0035] The cross-sectional area S1 of the first pillar 6 is the same as the cross-sectional area S2 of the second pillar 7. The cross-sectional area S1 of the first pillar 6 and the cross-sectional area S2 of the second pillar 7 are larger than the cross-sectional area S3 of the connecting conductor 8. The cross-sectional area S1 of the first pillar 6 is the cross-section at the smallest part of the first pillar 6. That is, the cross-sectional area S1 of the first pillar 6 is the cross-sectional area at the smallest part of the first pillar 6. The cross-sectional area S2 of the second pillar 7 is the cross-sectional area at the smallest part of the second pillar 7. That is, the cross-sectional area S2 of the second pillar 7 is the cross-sectional area at the smallest part of the second pillar 7.

[0036] The cross-sectional area S1 of the first pillar 6 is 0.02 times or more the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the first terminal electrode 3. The cross-sectional area S1 of the first pillar 6 is 0.02 times or more and 1.0 times or less the cross-sectional area of ​​the first terminal electrode 3, and preferably 0.05 times or more and 1.0 times or less. The cross-sectional area S2 of the second pillar 7 is 0.02 times or more the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the second terminal electrode 4. The cross-sectional area S2 of the second pillar 7 is 0.02 times or more and 1.0 times or less the cross-sectional area of ​​the second terminal electrode 4, and preferably 0.05 times or more and 1.0 times or less.

[0037] The inductor component 1 can be manufactured, for example, as follows: The base body 2 can be formed by laminating sheets that constitute the base body layer. The inductor 5 (first pillar 6, second pillar 7, connecting conductor 8) can be manufactured using photolithography. "Photolithography" refers to any method that processes a layer containing a photosensitive material into a desired pattern by exposure and development, and is not limited to the type of mask.

[0038] First, conductors constituting the connecting conductor 8 are formed on the sheet constituting the base layer using photolithography. Next, conductors constituting the first pillar 6 and the second pillar 7 are formed using photolithography, and then the sheet constituting the base layer is laminated. Subsequently, the sheet is polished by grinding to expose the conductors and flatten it. The first pillar 6 and the second pillar 7 are formed by repeating this process a predetermined number of times.

[0039] Next, the conductors constituting the first pillar 6 and the second pillar 7 are formed by photolithography, and then the sheet constituting the base layer is laminated. Subsequently, the sheet is polished by grinding to expose the conductors and flatten the sheet. Then, the first terminal electrode 3 and the second terminal electrode 4 are formed so as to connect to the first pillar 6 and the second pillar 7. Through the above steps, an inductor component 1 is obtained.

[0040] As explained above, in the inductor component 1 according to this embodiment, the cross-sectional area of ​​the cross section S1 of the first pillar 6 and the cross-sectional area of ​​the cross section S2 of the second pillar 7 are larger than the cross-sectional area of ​​the cross section S3 of the connecting conductor 8. In this way, in the inductor component 1, the inductance value of the inductor 5 can be reduced by making the cross-sectional area of ​​the cross section S1 of the first pillar 6 and the cross-sectional area of ​​the cross section S2 of the second pillar 7 larger than the cross-sectional area of ​​the connecting conductor 8. As a result, in the inductor component 1, the inductance value can be reduced and then adjusted by the connecting conductor 8. Therefore, the inductance value can be easily adjusted (set) in the inductor component 1.

[0041] In the inductor component 1 according to this embodiment, the base body 2 is made of a light-transmitting material. In this configuration, the internal structure of the base body 2 can be observed. Therefore, in the inductor component 1, based on the internal structure of the base body 2, it is possible to distinguish by visual inspection the surfaces of the base body 2 other than the main surface (mounting surface) 2d on which the first terminal electrode 3 and the second terminal electrode 4 are located.

[0042] In the inductor component 1 according to this embodiment, the connecting conductor 8 is positioned on the main body 2 closer to the main surface 2c than to the center in the second direction D2. In this configuration, because the connecting conductor 8 is positioned closer to the main surface 2c than to the center in the second direction D2, the connecting conductor 8 can be seen from the main surface 2c side when the main body 2 is made of a light-transmitting material. As a result, in the inductor component 1, it is possible to distinguish by sight the surfaces of the main body 2 other than the main surface 2d on which the first terminal electrode 3 and the second terminal electrode 4 are located.

[0043] In the inductor component 1 according to this embodiment, the width W1 of the first pillar 6, the width W2 of the second pillar 7, and the width W3 of the connecting conductor 8 are the same (W1=W2=W3). In this configuration, it is possible to suppress abrupt (sudden) changes in the cross-sectional area between the first pillar 6 and the connecting conductor 8, and between the second pillar 7 and the connecting conductor 8. As a result, the inductor component 1 can suppress a decrease in the Q value due to abrupt changes in the cross-sectional area.

[0044] In the inductor component 1 according to this embodiment, the cross-sectional area S1 of the first pillar 6 is 0.02 times or more the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the first terminal electrode 3. The cross-sectional area S2 of the second pillar 7 is 0.02 times or more the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the second terminal electrode 4. In this configuration, it is possible to suppress abrupt changes in the cross-sectional area between the first pillar 6 and the first terminal electrode 3, and between the second pillar 7 and the second terminal electrode 4. As a result, the inductor component 1 can suppress a decrease in the Q value due to abrupt changes in the cross-sectional area.

The other end of the first pillar 11 (the other end: the end on the main surface 2c side) is connected to the connecting conductor 13.

[0049] The second pillar 12 is positioned near the end face 2b of the base body 2 in the first direction D1. The second pillar 12 is positioned near the side surface 2e in the third direction D3. The first pillar 11 and the second pillar 12 are positioned opposite each other in the first direction D1. The second pillar 12 extends along the second direction D2. In this embodiment, the second pillar 12 has a prismatic shape.

The cross-sections of the connecting conductors 13 and 23 shown in Figure 10(c) are planes perpendicular to the first direction D1.

[0056] In this embodiment, the width W11 of the first pillars 11, 21, the width W12 of the second pillars 12, 22, and the width W13 of the connecting conductors 13, 23 are the same (W11=W12=W13). Widths W11, W12, and W13 are the widths in the third direction D3.

[0057] The cross-sectional area S11 of the first pillars 11 and 21 is the same as the cross-sectional area S12 of the second pillars 12 and 22. The cross-sectional area S11 of the first pillars 11 and 21, and the cross-sectional area S12 of the second pillars 12 and 22 are larger than the cross-sectional area S13 of the connecting conductors 13 and 23. The cross-sectional area S11 of the first pillars 11 and 21 is the cross-section at the smallest area of ​​the first pillars 11 and 21. That is, the cross-sectional area S11 of the first pillars 11 and 21 is the cross-sectional area at the smallest area of ​​the first pillars 11 and 21. The cross-sectional area S12 of the second pillars 12 and 22 is the cross-sectional area at the smallest area of ​​the second pillars 12 and 22.

[0058] The cross-sectional area S1 of the first pillars 11 and 21 is at least 0.02 times the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the first terminal electrode 3. The cross-sectional area S1 of the first pillars 11 and 21 is at least 0.02 times and less than or equal to 1.0 times the cross-sectional area of ​​the first terminal electrode 3, and preferably at least 0.05 times and less than or equal to 1.0 times. The cross-sectional area S2 of the second pillars 12 and 22 is at least 0.02 times the cross-sectional area of ​​the plane perpendicular to the second direction D2 of the second terminal electrode 4.

[0059] As explained above, in the inductor component 1A according to this embodiment, the cross-sectional area S11 of the first pillars 11 and 21, and the cross-sectional area S12 of the second pillars 12 and 22 are larger than the cross-sectional area S13 of the connecting conductors 13 and 23. In this way, in the inductor component 1A, the inductance values ​​of the inductors 10 and 20 can be reduced by making the cross-sectional areas of the first pillars 11 and 21, and the second pillars 12 and 22 larger than the cross-sectional areas of the connecting conductors 13 and 23. As a result, in the inductor component 1A, the inductance value can be reduced and then adjusted using the connecting conductors 13 and 23. Therefore, the inductance value can be easily adjusted (set) in the inductor component 1A.
