To obtain a parameter of a circuit element for transmitting an AC power having an angular frequency from a transmission antenna connected to a power supply circuit to a reception antenna at a distance with excellent efficiency and transmitting it to a load circuit, without trial and error.

The induced power transmission circuit includes: a circuit whose ends are connected by a capacitor C1, and in which a power supply circuit is connected in series to the transmission antenna of an effective self-inductance L1; and a circuit whose ends are connected by a capacitor C2, and in which a load circuit is connected in series to the reception antenna of an effective self-inductance L2. The distance between the transmission antenna and the reception antenna is set to be equal to or less than 1/2 of the wavelength of an electromagnetic field, in which power is transmitted. Regarding a phase angle having a value from 0 to radians, the angular frequency is set to the square root of the reciprocal of a value of L2C2(1+kcos()), the output impedance of the power supply circuit is set to approximately kL1sin()r1, and the input impedance of the load circuit is set to approximately kL2sin()r2.
