Abstract: Power reception device includes a plurality of secondary coils which interlinks with magnetic flux output by primary coil and at least one power reception side capacitor electrically connected to the plurality of secondary coils, and receives power without contact from power transmission device including primary coil. The plurality of secondary coils are connected in series to each other. Central axes of the plurality of secondary coils are oriented in mutually different directions. The plurality of secondary coils and power reception side capacitors configure one power reception side resonance circuit. According to the present aspect, power reception side resonance circuit can be easily designed, and a decrease of power transmission efficiency can be suppressed.
