A wireless power transmitting device includes a self-oscillator circuit, a detection circuit that detects at least one of an oscillation frequency of the self-oscillator circuit and an output voltage of the self-oscillator circuit, a detection resonator that outputs, to detect a position of the power receiving device, power output by the oscillation circuit, and a control circuit that detects a degree to which the power receiving device approaches the detection resonator, based on a result of a detection performed by the detection circuit. |
