A wireless power transfer device including: a power transmitter 1 including a power transmission resonator composed of a power transmission coil and a resonant capacitance; and a power receiver including a power receiving resonator composed of a power receiving coil and a resonant capacitance. The wireless power transfer device further includes a power-transmission auxiliary device including an auxiliary resonator composed of an auxiliary coil and a resonant capacitance. The power-transmission auxiliary device and the power transmitter are configured to be disposed so as to face each other, forming a power receiving space for disposing the power receiving coil between the power transmission coil and the auxiliary coil. An efficient power transfer can be performed without providing an adjusting circuit in the power receiver even when the power receiving coil is not appropriately disposed with respect to the power transmission coil.
