The wireless power transmission device (1) is a wireless power transmission device which wirelessly transmits electric power between a power-transmitting coil (L1) and a power-receiving coil (L2), and which includes: a metal member (M); a power supply unit (13) which supplies the electric power to the power-transmitting coil; a measurement unit (14) which measures a relative position of the power-receiving coil with respect to the power-transmitting coil; and a control unit (15) which controls the power supply unit. The control unit adjusts the electric power based on the relative position measured by the measurement unit, so that an amount of induced current flowing through the metal member is decreased. According to the present invention, it is possible to provide a wireless power transmission device and a wireless power transmission method which can reduce the amount of induced current flowing through a metal member even when the relative positional relationship between a power-transmitting coil and a power-receiving coil is changed, and which can suppress overheating of the metal member. |
