PROBLEM TO BE SOLVED: To provide a wireless power-receiving device and a wireless power transmission device that prevent damage of components constituting a circuit when failure occurs at the time of inputting high power and improve safety.SOLUTION: A wireless power-receiving device 100 comprises: voltage detection means 12 for detecting a voltage between a resistor RC and a switching element Q1; abnormality detection means 13 for detecting abnormality of the wireless power-receiving device 100 and transmitting a signal SE indicating the abnormal condition; and a control circuit 14 for controlling operation of a cut-off switch SW and the switching element Q1. The control circuit 14 controls the switching element Q1 to be a conduction state when receiving the signal SE indicating the abnormal condition transmitted from the abnormality detection means 13, and controls the cut-off element SW to be a non-conduct state and cuts off power when a voltage value VC detected by the voltage detection means 12 is lower than a preset reference voltage value. |
