Abstract
A wireless power transmission apparatus includes: a transmitter that wirelessly transmits electric power; and a receiver that can receive, in a resonant relation with the transmitter, a transmission signal including the electric power transmitted from the transmitter, wherein the receiver includes a frequency variable unit that can change a reception resonant frequency; a detecting unit that detects reception power; and a control unit that controls the frequency variable unit to perform frequency adjustment such that the reception power detected by the detecting unit is maximized.
