PROBLEM TO BE SOLVED: To enhance heat-dissipation effects on the power-receiving side in magnetic-field resonance type wireless power supply. SOLUTION: Power is transmitted from a feeding coil to a power-receiving coil L<SB>3</SB>by magnetic resonance. A capacitor C<SB>3</SB>is connected in series to the power-receiving coil L<SB>3</SB>so as to form a power-receiving-coil circuit. A load coil L<SB>4</SB>electromagnetically coupled with the power-receiving coil L<SB>3</SB>is connected with a load via a rectifying circuit 142 so as to form a load circuit. The rectifying circuit 142 is placed on a first flat-plate electrode 132 of the capacitor C<SB>3</SB>so as to relieve heat, generated from the rectifying circuit 142, to the first flat-plate electrode 132.
