A non-contact power transmission system includes a power receiving device (20) that includes a rectification circuit (23), a voltage converting circuit (24), and a switching circuit (26) for connecting or disconnecting the voltage converting circuit (24) to or from a load circuit (25), and a power transmitting device (10) that includes a power transmitting circuit (11), a detection circuit (15) that detects a current that is supplied to the power transmitting circuit (11), and a determination circuit (33) that compares the detected current value with a threshold current set in advance, and determines whether the load circuit (25) of the power receiving device (20) is in contact with the power transmitting device (10), where the power transmitting device (10) transmits power to the power receiving device (20) in a non-contact manner. |
