Abstract
A contactless power supply system includes: a power supply pad including a power supply core formed of a magnetic material, and a power supply coil that uses the power supply core as a magnetic path; and a filter circuit including an inductor coil, the filter circuit being connected to the power supply pad. The power supply pads to which the respective filter circuits are connected are brought into a face-to-face relation so that electric power is transmitted from one power supply pad to the other power supply pad in a contactless manner. An inductor coil of at least either one of the filter circuits is provided to the power supply core of the power supply pad to which the filter circuit is connected, and the inductor coil uses the power supply core as a magnetic path.
