    • An inductor includes a stacked body having a first through hole, and an insulation film covering the stacked body. The stacked body includes a first wiring, a first insulation layer stacked on the first wiring and including a second through hole exposing the first wiring, a first adhesive layer stacked on the first insulation layer and including a third through hole communicating with the second through hole, a second wiring stacked on the first adhesive layer and including a fourth through hole communicating with the third through hole, a second insulation layer stacked on the second wiring and including a fifth through hole communicating with the fourth through hole, and a first through electrode with which the second to fifth through holes are filled. The first and second wirings are connected to form a helical coil. The fifth through hole has a larger planar shape than the fourth through hole.

    • An inductor includes a stacked structure. The stacked structure includes a substrate, a first structural body stacked on a lower surface of the substrate, and second structural bodies sequentially stacked on an upper surface of the substrate. A through hole extends through the stacked structure in a thickness direction. An insulation film covers the stacked structure. The first structural body includes a first insulating layer stacked on the lower surface of the substrate, and a first wiring stacked on a lower surface of the first insulating layer. The second structural bodies include second insulating layers and second wirings. The first wiring and the second wirings are connected in series to one another to form a helical coil. The substrate has a thickness greater than that of the first insulating layer and the second insulating layers.
    • 电感器包括堆叠结构。 堆叠结构包括基板,堆叠在基板的下表面上的第一结构体和顺序地堆叠在基板的上表面上的第二结构体。 通孔在厚度方向上延伸穿过层叠结构。 绝缘膜覆盖堆叠结构。 第一结构体包括堆叠在基板的下表面上的第一绝缘层和堆叠在第一绝缘层的下表面上的第一布线。 第二结构体包括第二绝缘层和第二布线。 第一布线和第二布线彼此串联连接以形成螺旋线圈。 基板的厚度大于第一绝缘层和第二绝缘层的厚度。
