A wireless power transmission device includes: a power transmission antenna a radiation direction determiner; an orientation direction changer; and a transmission signal generator. The power transmission antenna is a phased array antenna including: a plurality of element antennas to radiate radio waves; and a plurality of element modules, each of the plurality of element modules including a phase shifter to change a phase of a transmission signal and an amplifier to amplify the transmission signal from the power transmission antenna. A phase offset value for the phase shifter included in each of the plurality of element modules is calculated by performing a REV (rotating element electric field vector) method using an aerial moving body hovering over the power transmission antenna and mounting a measurement antenna to receive a 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.
