A power receiving device includes: a ferrite member including a plurality of pieces of ferrite at least some of which are spaced from adjacent pieces of ferrite; a power receiving coil disposed on a lower surface side of the ferrite member; and a power receiving capacitor disposed on an upper surface side of the ferrite member. The power receiving capacitor has a closed loop circuit including first and second wiring connections and a plurality of capacitor elements connected in parallel between the first wiring connection and the second wiring connection. When the power receiving capacitor and the ferrite member are viewed from the lower surface side of the ferrite member, the closed loop circuit is located behind and within a perimeter of one of the pieces of ferrite. A power transmitting device has a mirror structure to the power receiving device.
