A radio power transmission apparatus comprises a transmitter 20 having a power transmitting antenna 9 for transmitting electromagnetic waves and a power transmitting circuit and a receiver 40 having a power receiving antenna 29 for receiving electromagnetic waves and a power receiving circuit. In the radio power transmission apparatus, on the basis of power reflected to the power transmitting antenna 9, the power transmitting circuit executes control to change the circuit reactance of the power transmitting circuit in order to control the imaginary part of power of the electromagnetic waves to be transmitted. In addition, on the basis of a value of power transmitted to the transmitter 20 by using electromagnetic waves of power transmission used by the receiver 40 to transmit a value of power received by the receiver 40 through the power receiving antenna 29, the power transmitting circuit executes control to change the circuit reactance of the power transmitting circuit or the characteristic impedance of the power transmitting circuit in order to control the real part of power of the electromagnetic waves to be transmitted.
