摘要： PROBLEM TO BE SOLVED: To detect a change in capacitance from a distant
position. SOLUTION: A receiving side coil 14 arranged at a predetermined distance from a transmitting side coil 10 and sharing a magnetic field, a target coil CL3 arranged between
the transmitting side coil 10 and the receiving side coil 14, and a capacitance are provided. The frequency is the power transmitted from the changing capacitor C3, which is the capacitor C3 connected to the target coil CL3 and determines the resonance frequency of the resonance circuit 12, and the current flowing through the transmitting side coil 10 and the receiving side coil 14. The capacitor C3 includes a resonance frequency detector (network analyzer 20) that analyzes and detects the resonance frequency of the resonance circuit from the pha change or loss of the transmission power due to the resonance of the resonance circuit 12, and is bad on the detected resonance frequency. Detects the capacity of. [Selection diagram] Fig. 2
