Abstract

A power receiving device includes: a power receiving unit that receives electric power from an externally provided power transmitting unit contactlessly; and a casing having the power receiving unit accommodated therein, the casing including: a lid member located on the power transmitting unit's side and allowing a magnetic field to pass therethrough, and a plurality of temperature sensors provided at the lid member and sensing in temperature a foreign matter present between the power transmitting unit and the power receiving unit, the temperature sensors being spaced closer together at the location of a strong portion of an electromagnetic field strength generated from the power receiving unit than the location of a weak portion of the electromagnetic field strength generated from the power receiving unit.
