Coil

摘要

A coil which maintains a balance of a parasitic capacitance and has a structure that can be multilayered. The coil is stacked with a structure which includes winding wire portions formed of a wire wound for several turns in a plane in each layer, wherein winding wire portions in each layer include a first winding portion formed by performing a single turn of winding in each layer in a same winding direction from a bottom layer to an uppermost layer, and a second winding portion formed by performing a single turn of winding in each layer in a same winding direction from the uppermost layer to the bottom layer, and the winding directions of the first and second winding portions are identical to each other and the first winding portion and the second winding portion are joined in the uppermost layer or the bottom layer.

主权项

1. A coil with a stacked structure, comprising:
a bobbin which comprises a plate portion for separating a wire-accommodating portion in each layer, and a winding wire portion which comprises a wire wound multiple times in a plane and is accommodated in the wire-accommodating portion in each layer, wherein the winding wire portion includes a first winding portion formed by performing a single turn of winding in each layer in a same winding direction from a bottom layer to an uppermost layer of the wire-accommodating portions, and a second winding portion formed by performing a single turn of winding in each layer in a same winding direction from the uppermost layer to the bottom layer of the wire-accommodating portions, and the winding directions of the first winding portion and the second winding portion are identical to each other, and the first winding portion and the second winding portion are joined in the uppermost layer or the bottom layer of the wire-accommodating portions.
