Abstract:
A power-transmission-side coil unit includes: a housing including a metal case body and a resin cover, an electric device provided in the housing, a metal substrate disposed between the cover and the electric device and covering the electric device, and a power transmission coil. The case body includes a base portion, and a ring-shaped wall portion protruding toward the cover along the outer peripheral edge of base portion inside the outer peripheral edge of base portion. The metal substrate includes a partition wall disposed between the cover and the electric device, and a peripheral wall extending from the partition wall toward the base portion. An end portion of the peripheral wall is disposed in the D direction relative to the upper face of the ring-shaped wall portion. At least part of a lateral face of the peripheral wall is in contact with a lateral face of the ring-shaped wall portion.
