POWER-RECEIVING DEVICE

摘要

This power-receiving device (200) is provided with a plate-shaped core (240) and a coil (250) wound around said core in a helical fashion, the central axis around which said coil is wound being horizontal. The coil is made plate-shaped so as to have long sides (251) and short sides (252) in a cross-section in a plane perpendicular to the direction in which the coil extends. The coil is wound around the core such that a long side of the coil faces the surface of the core, making it possible to reduce the thickness of this power-receiving device.
