[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-141945 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of one aspect of the present invention is to provide a coil component that can suppress the occurrence of short circuits in the coil. [Means for solving the problem]

[0005] A coil component according to one aspect of the present invention includes an element body including a first main surface and a second main surface facing each other, a first side surface and a second side surface facing each other, and a third side surface and a fourth side surface facing each other, and a coil disposed within the element body. The coil includes a first conductor layer positioned to face the first main surface and a second conductor layer positioned to face the second main surface. The first conductor layer includes a plurality of first conductors aligned in a direction in which the third side surface and the fourth side surface face each other. Each of the plurality of first conductors includes a first conductor portion positioned closer to the first side surface, a second conductor portion positioned closer to the second side surface and corresponding to the first conductor portion, and a third conductor portion connecting the first conductor portion and the second conductor portion. The second conductor layer includes a conductor including an end connected to a first conductor portion included in a corresponding first conductor among the plurality of first conductors, and an end connected to a second conductor portion included in a first conductor adjacent to the corresponding first conductor. In each of the plurality of first conductors, the positions of the first conductor portion and the second conductor portion in the above direction are shifted from each other, and the third conductor portion extends in a direction different from the direction in which the first conductor portion and the second conductor portion extend. Of the plurality of first conductors, in two adjacent first conductors, the minimum distance between the third conductor portions is greater than the minimum distance between the first conductor portions and the minimum distance between the second conductor portions.

[0006] In one of the above aspects, in each of the multiple first conductors, the positions of the first conductor portion and the second conductor portion in the direction in which the third side surface and the fourth side surface face each other are offset from each other, and the third conductor portion extends in a direction different from the direction in which the first conductor portion and the second conductor portion extend. A configuration in which the spacing between the first conductors is large makes it less likely for a short circuit to occur in the coil than a configuration in which the spacing between the first conductors is small. In the above-mentioned aspect in which the third conductor portions extend in different directions, the spacing between the third conductor portions can be easily adjusted. For example, in a configuration in which the spacing between the third conductor portions is larger than the spacing between the first conductor portions, the spacing between the first conductors can be partially increased compared to a configuration in which the spacing between the third conductor portions is the same as the spacing between the first conductor portions. For example, in a configuration in which the spacing between the third conductor portions is larger than the spacing between the second conductor portions, the spacing between the first conductors can be partially increased compared to a configuration in which the spacing between the third conductor portions is the same as the spacing between the second conductor portions. In a configuration in which the minimum distance between the third conductor portions is greater than the minimum distance between the first conductor portions and the minimum distance between the second conductor portions, the spacing between the third conductor portions is greater than the spacing between the first conductor portions and is also greater than the spacing between the second conductor portions. Therefore, this aspect can suppress the occurrence of short circuits in the coil.

[0007] In one aspect, the plurality of first conductors may include a pair of first conductors and at least one first conductor located between the pair of first conductors, and the at least one first conductor may have a width smaller than each of the pair of first conductors. In a configuration in which at least one first conductor has a width smaller than each of the pair of first conductors, the spacing between the first conductors can be increased, which can further reduce the occurrence of short circuits in the coil.

[0008] In one of the above aspects, the conductor included in the second conductor layer may include a fourth conductor including an end connected to a first conductor portion included in at least one first conductor, and a fifth conductor including an end connected to a second conductor portion included in at least one first conductor. The coil may include a first connecting conductor connecting a first conductor portion included in at least one first conductor and the fourth conductor, and a second connecting conductor connecting a second conductor portion included in at least one first conductor and the fifth conductor. The first conductor portion and the first connecting conductor may each include an end region connected to each other and having the same area. The second conductor portion and the second connecting conductor may each include an end region connected to each other and having the same area. In a configuration in which the coil includes an end region, the first conductor layer and the second conductor layer can be securely connected to each other via the end region.

[0009] In the above-mentioned one aspect, in at least one first conductor, the third conductor portion may have a width greater than the widths of the first conductor portion and the second conductor portion. The inductance value of the coil component depends on the width of the first conductor. In a configuration in which the third conductor portion has a width greater than the widths of the first conductor portion and the second conductor portion, the inductance value of the coil component can be adjusted.

[0010] In the above one aspect, each of the plurality of first conductors may have the same width throughout the entirety of each of the plurality of first conductors. In the above one aspect, the angle formed between the first conductor portion and the third conductor portion and the angle formed between the second conductor portion and the third conductor portion may be less than 180 degrees. In the one aspect, the angle formed between the first conductor portion and the third conductor portion, and the angle formed between the second conductor portion and the third conductor portion may be 90 degrees. The one aspect above may include an external electrode connected to the coil and disposed on the first main surface. [Effects of the Invention]

[0011] One aspect of the present invention provides a coil component that can suppress the occurrence of short circuits in the coil. [Brief explanation of the drawings]

Figs. 4 and 5 are diagrams showing the configurations of the first conductor layer, the second conductor layer, and the connecting conductor. Fig. 6 is a diagram showing the cross-sectional configuration of the coil component according to this embodiment.

[0015] As shown in FIGS. 1 to 6 , the coil component ED1 includes an element body 1, external electrodes 10 and 20, a coil 30, and connecting conductors 35 and 36. The external electrodes 10 and 20 are disposed on the element body 1. The coil 30 is disposed within the element body 1 and is electrically connected to the external electrodes 10 and 20. The connecting conductor 35 electrically connects one end of the coil 30 to the external electrode 10. The connecting conductor 36 electrically connects the other end of the coil 30 to the external electrode 20.

[0016] The element body 1 has, for example, a rectangular parallelepiped shape. In this specification, the rectangular parallelepiped shape includes a rectangular parallelepiped shape with chamfered corners and ridges, or a rectangular parallelepiped shape with rounded corners and ridges. The element body 1 includes mutually opposing main surfaces 1a and 1b, mutually opposing side surfaces 1c and 1d, and mutually opposing side surfaces 1e and 1f. Side surfaces 1c and 1d, and side surfaces 1e and 1f connect the main surfaces 1a and 1b. In this embodiment, the surface of the element body 1 includes the main surfaces 1a and 1b and four side surfaces 1c, 1d, 1e, and 1f. For example, when main surface 1a includes the first main surface, main surface 1b includes the second main surface. For example, when side surface 1c includes the first side surface, side surface 1d includes the second side surface. For example, when side surface 1e includes the third side surface, side surface 1f includes the fourth side surface.

[0017] The principal surfaces 1a and 1b face each other in the first direction D1. The principal surface 1a is perpendicular to the first direction D1. The side surfaces 1c and 1d face each other in the second direction D2. The side surfaces 1e and 1f face each other in the third direction D3.

The side surfaces 1d and 1f are adjacent to each other.

[0018] The length of the element body 1 in the first direction D1 is, for example, 0.1 to 1 mm. The length of the element body 1 in the second direction D2 is, for example, 0.1 to 2 mm. The length of the element body 1 in the third direction D3 is, for example, 0.1 to 1 mm. In the element body 1, the second direction D2 is, for example, the long side direction. The second direction D2 intersects with the first direction D1. The third direction D3 intersects with the first direction D1 and the second direction D2. In this embodiment, the first direction D1, the second direction D2, and the third direction D3 are perpendicular to one another.

[0019] In this embodiment, the principal surface 1a constitutes a mounting surface. When the coil component ED1 is mounted on another electronic device, such as a circuit board or a laminated electronic component, the principal surface 1a faces the other electronic device. The principal surfaces 1a and 1b and the four side surfaces 1c, 1d, 1e, and 1f each have, for example, a rectangular shape. In this specification, a rectangular shape includes a shape with chamfered corners or a shape with rounded corners.

[0020] The element body 1 includes, for example, a plurality of insulator layers having electrical insulation properties. In this embodiment, the element body 1 includes a plurality of insulator layers stacked in a first direction D1. The plurality of insulator layers are integrated to the extent that the boundaries between them are practically invisible. Each of the plurality of insulator layers has, for example, a rectangular shape when viewed from the first direction D1.

[0021] The insulator layer is made of, for example, a sintered ceramic green sheet containing a ferrite material. The ferrite material includes, for example, a Ni-Cu-Zn ferrite material, a Ni-Cu-Zn-Mg ferrite material, or a Ni-Cu ferrite material. The insulator layer may include an Fe alloy.

[0022] The external electrodes 10 and 20 are arranged on the main surface 1a. The external electrodes 10 and 20 are joined to terminals of another electronic device when the coil component ED1 is mounted. The external electrodes 10 and 20 are arranged spaced apart from each other in the second direction D2. The external electrode 10 is located closer to the side surface 1c than the external electrode 20, and the external electrode 20 is located closer to the side surface 1d than the external electrode 10. When viewed from the first direction D1, the external electrodes 10 and 20 are spaced apart from the four ends of the element body 1 when viewed from the first direction D1. When viewed from the first direction D1, each of the four ends of the element body 1 overlaps with the corresponding side surfaces 1c, 1d, 1e, and 1f. The external electrodes 10 and 20 have, for example, a rectangular parallelepiped shape. The external electrodes 10 and 20 may be arranged on the main surface 1b. In this case, the main surface 1b constitutes, for example, a mounting surface.

[0029] Each of the three conductors 31a, 31b, and 31c includes a conductor portion P1, a conductor portion P2, and a conductor portion P3. The conductor portion P1 is located closer to the side surface 1c. The conductor portion P2 is located closer to the side surface 1d.

The conductor portion P3 extends in a direction different from the direction in which the conductor portion P1 and the conductor portion P2 extend. In the present embodiment, the conductor portion P3 extends in the third direction D3. The conductor portion P3 may extend in a curved manner. In the conductors 31a, 31b, and 31c extending in the third direction D3, the angle AG1 between the conductor portion P1 and the conductor portion P3 and the angle AG2 between the conductor portion P2 and the conductor portion P3 are, for example, 90 degrees. The conductor portion P1 is continuous with the conductor portion P3. The conductor portion P3 is continuous with the conductor portion P2. The angle AG1 may be the same as the angle AG2 or may be different from the angle AG2.

For example, when the conductor portion P1 includes a first conductor portion, the conductor portion P2 includes a second conductor portion, and the conductor portion P3 includes a third conductor portion. For example, the conductors 31a, 31b, and 31c include a first conductor.
