A power transmitting device includes a resonance circuit, a first signal generating unit, and a second signal generating unit. The resonance circuit is used in non-contact power transmission. The first signal generating unit is connected to one end of the resonance circuit, and generates, with the use of a switching system, a first high-frequency signal including one or more harmonic components. The second signal generating unit is connected to an other end of the resonance circuit, and generates, with the use of a switching system, a second high-frequency signal including a specific harmonic component. The first high-frequency signal is adjusted in pulse width and input to the one end of the resonance circuit, and the second high-frequency signal is adjusted in pulse width and phase difference from the first high-frequency signal and input to the other end of the resonance circuit.
