Abstract

An electrically powered vehicle is provided with a vehicle body having a bottom surface, a battery disposed inside the vehicle body, a power receiving device configured to receive electrical power in a non-contact manner from a power transmission coil of a power transmission device disposed outside the vehicle body when facing the power transmission coil, and an electrical apparatus electrically connected to the power receiving device and the battery for supplying power received from the power receiving device to the battery. The power receiving device includes a power receiving coil disposed on the bottom surface of the vehicle body, and a capacitor disposed inside the vehicle body and electrically connected to the power receiving coil and the electrical apparatus. Thereby, the impact of heat on the capacitor included in the power receiving device can be suppressed.
