Abstract: Provided is a wireless-power transfer apparatus capable of efficiently supplying a predetermined power for each of plural terminal apparatuses. A wireless-power transfer apparatus comprises a radio processing section for transmitting a signal for wireless power transfer to each of the plural terminal apparatuses via plural beams, by a beamforming for forming the plural beams against the plural terminal apparatuses simultaneously or at staggered times, an information acquisition section for acquiring terminal information including location information of a current location of a terminal apparatus for each of plural terminal apparatuses, and a control section for controlling the beamforming so that a signal for wireless power transfer is received at a predetermined reception power in each of plural terminal apparatuses, based on terminal information of each of plural terminal apparatuses.
