1. An aerial moving body comprising:
a rotary blade to generate lift by rotating;
an airframe on which the rotary blade is provided;
a power reception antenna including a power reception surface to receive a radio wave transmitting electric power, the power reception surface having an area larger than an area projecting the airframe onto a rotation axis perpendicular plane, the rotation axis perpendicular plane being a plane perpendicular to a rotation axis direction, the rotation axis direction being a direction parallel to a rotation axis of the rotary blade, and a drag reducing structure to reduce a drag caused by a descending airflow generated by rotation of the rotary blade:
a converter to convert electric power of the radio wave received by the power reception antenna into DC electric power;
a storage battery to store the DC electric power; and
an electric motor to which the DC electric power converted by the converter or the DC electric power stored in the storage battery is supplied, and to generate power to rotate the rotary blade.
