In this power transmission system, the power-transmitting device and the power-receiving device are each provided with a resonance coil that performs the power transmission wirelessly underwater by means of magnetic field resonance. At least one of the power-transmitting device and the power-receiving device is provided with a balloon that internally houses the resonance coil of its own device.
