Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A coil with a stacked structure which comprises a winding wire portion formed of a wire wound multiple times in a plane in each layer, wherein the winding wire portion in each layer 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 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 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. 2 . The coil of claim 1 , wherein, the winding wire portions in the adjacent upper and lower layers face each other via an insulating member. 3 . The coil of claim 2 , wherein, the insulating member is a planar member provided with a slit, and the wires of the winding wire portion in the adjacent upper and lower layers are joined via the slit.
