Antenna apparatus and electronic timepiece

An antenna apparatus includes, a ring-shaped antenna element positioned on a first plane; a grounding conductive plate positioned on a second plane parallel to the antenna element; a conductive member that is positioned on a side farther from a center position of the first plane enclosed by an outer periphery of the antenna element; and a power supply terminal. The power supply point is positioned in a predetermined nearby range from a boundary between a first region and a second region that include first and second angle ranges symmetrical with relation to the center position. The conductive member is positioned in at least one of the first region and the second region, and is provided in a position in which a spreading width from the center position in a distance direction are made different between the first region and the second region by the antenna element and the conductive member.
