Claim Text:
1. An electric power transmission apparatus comprising: a resonance circuit that is used for contactless electric power transmission; a first signal generation unit that is connected to one end of the resonance circuit, and is configured to generate a first high-frequency signal which includes one or more harmonic components using a switching method; and a second signal generation unit that is connected to another end of the resonance circuit, and is configured to generate a second high-frequency signal which includes a specific harmonic component using the switching method, wherein the first high-frequency signal is input to the one end of the resonance circuit, and the second high-frequency signal is input to the another end of the resonance circuit, and wherein a frequency of the second high-frequency signal which is generated by the second signal generation unit is a value which is obtained by increasing a frequency of the first high-frequency signal to a multiple of a predetermined number.
