A contactless power receiving device includes a power receiving coil receiving power from a contactless power transfer device, a rectifier circuit rectifying the power to form a rectified output on a high potential side and a rectified output on a low potential side, a smoothing circuit receiving the rectified output on the high potential side and the rectified output on the low potential side, and a switching power supply converting a DC voltage from the smoothing circuit to a first voltage. The smoothing circuit includes a first inductor transmitting the rectified output on the high potential side, a second inductor transmitting the rectified output on the low potential side, and a smoothing capacitance element to which the rectified output on the high potential side and the rectified output on the low potential side are supplied, and the rectified output on the low potential side is connected to a ground potential.
