PROBLEM TO BE SOLVED: To provide a detector capable of correctly detecting a foreign matter in a magnetic field.SOLUTION: The measuring coil includes: a first partial coil that induces a current in a specific direction with the magnetic field applied to the power reception coil for receiving the power; a second partial coil that induces a current in a specific direction with the magnetic field; and a third partial coil which is disposed between the first partial coil and the second the partial coil for inducing a current in a direction opposite to the specific direction with the magnetic field. The measurement section measures the voltage from a measuring coil as measured coil voltage. The foreign matter detection section detects a foreign matter in the magnetic field based on the measured coil voltage. |
