Abstract
A second resonant type transmission power supply deviceincludes a transmission power state detecting circuitthat detects a transmission power state of a second transmission antenna, a foreign object detecting circuitthat detects the presence or absence of a foreign object in an overlapping range of electromagnetic fields on the basis of a detection result acquired by the transmission power state detecting circuit, and a power control circuitthat, when a foreign object is detected by the foreign object detecting circuit, controls a first resonant type transmission power supply devicein such a way as to reduce or stop the supply of electric power to a first transmission antenna
