A wireless power transmission device includes: a power transmission antenna to transmit power with a radiating radio wave and being capable of changing an orientation direction; a radiation direction determiner to determine a radiation direction, the radiation direction being a direction in which an aerial moving body exists, the aerial moving body being a power transmission target; an orientation direction changer to direct the orientation direction of the power transmission antenna toward the radiation direction; and a transmission signal generator to generate a transmission signal transmitted as the radio wave from the power transmission antenna. The power transmission antenna is a phased array antenna including: a plurality of element antennas to radiate the radio wave; and a plurality of element modules, each of the plurality of element modules including a phase shifter to change a phase of the transmission signal and an amplifier to amplify the transmission signal. The orientation direction changer controls a phase command value for the phase shifter. A phase offset value for each phase shifter is determined by a REV (rotating element electric field vector) method using an aerial moving body that hovers above the power transmission antenna, and the aerial moving body is mounted with a measurement antenna to receive the radio wave and a radio wave measurer to measure received radio wave data including an amplitude of the radio wave received by the measurement antenna.
