1. A power reception device, comprising:
- a flat plate-like core; and
a coil spirally wound around the core and having a winding central axis extending in a horizontal direction,the coil being formed like a flat plate to have a longer side portion and a shorter side portion when the coil is viewed in cross section at a plane perpendicular to an extending direction of the coil,the coil being wound around the core such that the longer side portion faces a surface of the core, andthe coil being wound around the core in a multi-layer winding manner.

Abstract
A power reception device includes a flat plate-like core and a coil spirally wound around the core and having a winding central axis extending in a horizontal direction. The coil is formed like a flat plate to have a longer side portion and a shorter side portion when the coil is viewed in cross section at a plane perpendicular to an extending direction of the coil. The coil is wound around the core such that the longer side portion faces a surface of the core. Therefore, the thickness of the power reception device can be reduced.
