PROBLEM TO BE SOLVED: To provide a non-contact power supply system which is miniaturized and can be manufactured at a low cost.SOLUTION: A non-contact power supply system includes: a power transmission device including a first AC power source for generating AC power with a first frequency, a second AC power source for generating AC power with a second frequency different from the first frequency, a first electromagnetic induction coil, and a first resonance coil; and a power reception device including a second resonance coil, a second electromagnetic induction coil, and a power storage device. By resonating the first electromagnetic induction coil and the second electromagnetic induction coil by electromagnetic induction, wireless communication is performed at the first frequency. By causing a magnetic field resonance phenomenon between the first resonance coil and the second resonance coil, the power storage device is wirelessly supplied with power at the second frequency.SELECTED DRAWING: Figure 1 |
