PROBLEM TO BE SOLVED: To provide an inductive power supply system using a resonant antenna system that matches at a relatively low impedance and efficiently transmits spacial power. SOLUTION: At least either of a transmitting antenna and a receiving antenna transmits spacial energy via an endpoint having antenna obtained by winding a wire having both ends in a coil shape and connecting a feeder line to a midpoint of the wire. This makes it possible to match impedance with a slightly low value with which the impedance can be easily matched with the impedance of the power supply circuit of an electronic device connected to the antenna for energy transmission. The matched impedance can be controlled by adding an additional loop wire in parallel to the feeding point of the endpoint having antenna at which the feeder line is connected.
