## Abstract

Disclosed herein is a wiring component that includes a base material and a planar coil pattern formed on the base material. The planar coil pattern includes a coil wiring portion having one end, other end, and first to third connecting positions, the second connecting position being closer to the other end compared with the first connecting position, the third connecting position being closer to the one end compared with the second connecting position; a power-feed wiring portion connected to the first connecting position; and a connection wiring portion that short-circuits the second connecting position and the third connecting position. A cross-section structure of the planar coil pattern has a base resin layer formed on the base material, and a conductive layer formed on the base resin layer.

## Claims

### Claim 1

A wiring component comprising:
a base material; and
a planar coil pattern formed on the base material,
wherein the planar coil pattern includes:
a coil wiring portion having one end, other end, and first to third connecting positions, the second connecting position being closer to the other end compared with the first connecting position, the third connecting position being closer to the one end compared with the second connecting position;
a power-feed wiring portion connected to the first connecting position; and
a connection wiring portion that short-circuits the second connecting position and the third connecting position, and
wherein a cross-section structure of the planar coil pattern has a base resin layer formed on the base material, and a conductive layer formed on the base resin layer.

### Claim 2 (depends on 1)

The wiring component as claimed in claim 1,
wherein the coil wiring portion includes a spiral pattern, and
wherein the one end and the other end of the coil wiring portion are an outer peripheral end and an inner peripheral end of the spiral pattern, respectively.

### Claim 3 (depends on 2)

The wiring component as claimed in claim 2, wherein the second connecting position is located at the inner peripheral end of the spiral pattern.

### Claim 4 (depends on 2)

The wiring component as claimed in claim 2, wherein the third connecting position is located at a cross point of an innermost turn of the spiral pattern and an extension line extending from the inner peripheral end in a winding direction.

### Claim 5 (depends on 2)

The wiring component as claimed in claim 2, wherein the first connecting position is apart from the outer peripheral end and located on an outermost turn of the spiral pattern.

### Claim 6 (depends on 1)

The wiring component as claimed in claim 1, wherein the base material comprises a resin film.

### Claim 7 (depends on 1)

The wiring component as claimed in claim 1, wherein the base resin layer includes at least one of metal selected from Pd, Cu, Ni, Ag, Pt, and Au.

### Claim 8 (depends on 1)

The wiring component as claimed in claim 1, wherein the conductive layer includes a base conductive layer formed on the base resin layer by electroless plating, and a wiring conductive layer thicker than the base conductive layer, formed on the base conductive layer by electrolytic plating.

### Claim 9 (depends on 8)

The wiring component as claimed in claim 8, wherein each of the base conductive layer and the wiring conductive layer comprises at least one of metal selected from Cu, Ag, and Au, respectively.
