Abstract
This electrical power-receiving apparatus makes it possible to suppress a decline in power supply efficiency in a variety of different circumstances while avoiding an increase in circuit scale. This apparatus comprises an impedance control unit () for sequentially switching through any one of a plurality of charging devices in a charging device group (), as candidate charging devices for a supply destination to which electrical power is to be supplied. The impedance control unit () also selects from the candidates a charging device to which electrical power is actually supplied, on the basis of the difference between the impedance of the charging device group () for each candidate and the impedance of an electrical power receiving antenna unit (), and causes electrical power to be supplied to the selected charging device.
