Zusammenfassung:	A wireless power transmission antenna apparatus (100, 200) is mounted on a wireless power transmitting apparatus configured to transmit electric power in a wireless manner, and is provided with: an antenna coil (10) obtained by winding a conductive member; a plurality of plate-like members (21, 22, 23, 24), each containing metal and disposed in surroundings of the antenna coil and in a radial direction of the antenna coil; and a housing case (30) containing metal and configured to accommodate therein the antenna coil and the plurality of plate-like members. The plate-like member is disposed such that a plate face thereof crosses a direction of extension of the conductive member. According to the wireless power transmission antenna apparatus, it is possible to improve power transmission efficiency while complying with radio wave protection guidelines.
