    Abstract: Disclosed herein is an antenna device that includes a planar coil pattern having first, second, third and fourth sections, the first and second sections being opposite to each other, and the third and fourth sections being opposite to each other, and a metal layer having at least one aperture. A part of the first section and a part of the second section overlap the metal layer, and a remaining part of the first section and a remaining part of the second section overlap the aperture. A part or an entirety of both the third and fourth sections overlaps the metal layer or the aperture.

    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.
