Abstract
A foreign matter detection device of the present invention is provided with a temperature detection means that detects a temperature distribution in a magnetic field that is formed by a power-supplying device that transmits power wirelessly to a power-receiving device; and a signal processor that, based on a detection result from the temperature detection means, detects a conductive foreign matter in the magnetic field.
