Abstract: The purpose of the present invention is to provide a contactless charging device which reduces magnetic field leaking from an air gap between a primary coil and a secondary coil so as to suppress radiation noise in contactless electrical power transmission. The device is provided with a power supply device (1) comprising a primary coil (13) which generates a magnetic field by way of a supply current from a power supply (2), and a power receiving device (8) comprising a secondary coil (15) which receives power by way of the magnetic field from the primary coil (13). The primary coil (13) and the secondary coil (15) are formed by winding coil wires, and the number of turns of the secondary coil (15) is set to be greater than the number of turns of the primary coil (13).

Abstract: A foreign object detector includes a detection coil; a transmitting circuit generating an unbalanced signal; a balanced-to-unbalanced transformer transforming the unbalanced signal supplied from the transmitting circuit to a balanced signal; and detection circuit detecting a foreign object by sensing a change in frequency characteristic of reflected power that is a power component reflected by the detection coil. The foreign object detector detects a foreign object while preventing a wire between the detection coil and the detection circuit from functioning as a linear antenna even if the wire is long.
