A power receiving device installable to a vehicle and included in a contactless power supply system for supplying power in a contactless manner between the power receiving device and a power transmission device installable on a road includes: polyphase receiver coils having at least three phases; an iron core that provides magnetic flux coupling between the receiver coils for the respective phases; and receiver capacitors connected on a one-to-one basis to the receiver coils for the respective phases. The receiver coils for the respective phases are arranged to have inter-coil distances between the receiver coils, with at least one of the inter-coil distances different from the other inter-coil distances. The receiver capacitors have capacitances set based on the inter-coil distances.
