A power transmitting unit (240) transmits AC transmission power to a power receiving unit (310) in a non-contact manner. An inverter (220) is configured to tune a transmission power frequency at a first frequency interval. A filter circuit (230) includes a capacitor and is configured to tune a resonance frequency of the power transmitting unit (240) at a second frequency interval which is larger than the first frequency interval. A power supply ECU (250) controls the inverter (220) and the capacitor such that the number of tunings of the transmission power frequency using the inverter (220) is larger than the number of tunings of the resonance frequency using the capacitor.
