PROBLEM TO BE SOLVED: To provide a non-contact power transmission device that can detect abnormality of a secondary coil, a rectification unit, and the like without relying on radio communication and that can quickly shift to safe operation.SOLUTION: A non-contact power transmission device comprises: a ground side coil 13 for generating a magnetic field by supply current from a power control device 7; a current transformer 23 for detecting the amplitude of input from the power control device 7; a power supply device side control unit 6 for controlling supply current to the ground side coil 13 from the power control device 7 on the basis of a detection signal from the current transformer 23; and a vehicle side coil 15 for receiving power by the magnetic field from the ground side coil 13. The power supply device side control unit 6 stops power supply to the ground side coil 13 when detecting an input change equal to or more than a prescribed value on the basis of the detection signal from the input detection unit 23. |
