INDUCTOR DEVICE AND ELECTRONIC APPARATUS |
摘要 |
An inductor device includes a layer-laminated member with laminated base-material layers and a coil with a winding axis coincident with a direction of layer lamination, a smaller-thickness portion near one end portion thereof in the direction of layer lamination, and a greater-thickness portion with more base-material layers than that in the smaller-thickness portion. The coil is located in the greater-thickness portion. The coil is connected, at its one end positioned near one end portion of the layer-laminated member, to a conductor pattern in the smaller-thickness portion. The coil is connected, at its other end positioned near the other end portion of the layer-laminated member, to a conductor pattern in a base-material layer located near the other end portion of the layer-laminated member. The conductor patterns are located at respective different positions in the direction of layer lamination. |

1. An inductor device comprising:
a layer-laminated member including base-material layers laminated; and a coil located in the layer-laminated member with a winding axis coincident with a direction of layer lamination; wherein the layer-laminated member includes a smaller-thickness portion positioned near one end portion thereof in the direction of layer lamination, and a greater-thickness portion with a greater number of base-material layers laminated therein than that in the smaller-thickness portion; the coil is located in the greater-thickness portion; the coil is connected, at one end positioned near one end portion of the layer-laminated member, to a first terminal portion in the smaller-thickness portion; the coil is connected, at the other end positioned near the other end portion of the layer-laminated member, to a second terminal portion in a base-material layer located near the other end portion of the layer-laminated member; and the first terminal portion and the second terminal portion are located at respective different positions in the direction of layer lamination. |
