PROBLEM TO BE SOLVED: To provide a non-contact power-feeding system using transmission and reception coils that allows feeding power and detecting the positions of the transmission and reception coils in real-time.SOLUTION: A first power-feeding circuit 14 and a first position detection circuit 20 are connected to a transmission coil 10, and a second power-feeding circuit 16 and a second position detection circuit 22 are connected to a reception coil 12. The first power-feeding circuit 14 and the second power-feeding circuit 16 include resonant circuits that resonant the transmission coil 10 and the reception coil 12 by a resonant frequency fp to feed power. The first position detection circuit 20 and the second position detection circuit 22 include means for resonating the transmission coil 10 and the reception coil 12 by a resonant frequency fd different from the resonant frequency fp and for detecting the mutual position of the transmission coil 10 and the reception coil 12. |
