  "textContent": "Provided is a wireless power transmission device that detects an abnormality of, for example, a secondary coil and a rectifier unit independently of wireless communication and can quickly shift to a safe operation. This device comprises: a ground-side coil (13) for generating a magnetic field by current supplied from a power control device (7); a current transformer (23) for detecting the magnitude of an input from the power control device (7); a power supplying device-side control unit (6) for, based on a detection signal from the current transformer (23), controlling the current supplied from the power control device (7) to the ground-side coil (13); and a vehicle-side coil (15) for receiving power via the magnetic field coming from the ground-side coil (13). When detecting an input change having a predetermined value or more on the basis of the detection signal from the input detection unit (23), the power supplying device-side control unit (6) stops the current supplied to the ground-side coil (13).",
