PROBLEM TO BE SOLVED: To provide a power receiving device that can correctly detect foreign matter.SOLUTION: A power receiving device includes: a power receiving coil configured to receive power when a power feeding device supplies the power via a magnetic field; an alternating-current power supply configured to apply an alternating voltage to the power receiving coil; and a foreign matter detecting section configured to generate an amount of change in impedance of the power receiving coil from the alternating voltage and a current that is induced in the power receiving coil to which the alternating voltage is applied, and detect foreign matter between the power receiving coil and the power feeding device on the basis of the amount of change. |
