Original Abstract Submitted

A contactless power transmission system includes a power transmitting unit, a power transmission power conversion unit, and a power transmission side control device. The power transmitting unit has a primary coil for sending out AC power to be transmitted to a power receiving device in a non-contact manner. The power transmission power conversion unit has a plurality of transistors connected to the primary coil. The power transmission power conversion unit converts a DC power supplied from a power source unit to an AC power. The power transmission side control device sets transmission power at a start period of initial power transmission by the power transmitting unit to less than a predetermined power. The power transmission side control device changes the transmission power in a tendency of increasing toward a predetermined power as a time elapses from a start of power transmission by the power transmitting unit.
