NON-CONTACT POWER SUPPLY DEVICE

摘要

This non-contact power supply device comprises: a primary side electric power transmission device (60) that includes a primary coil (61) that receives supplied electric power and generates alternating magnetic flux; a secondary side power-receiving device (70) that includes a secondary coil (71) that receives the magnetic flux from the primary coil (61) and generates an induced electric current; and a sensor (63) that detects changes in the state. The non-contact power supply device further comprises: a first magnetic substance (110) provided in the primary side electric power transmission device (60) in correspondence with the primary coil (61); and a second magnetic substance (120) provided in the secondary side power-receiving device (70) in correspondence with the secondary coil (71). At least one of the first magnetic substance (110) and the second magnetic substance (120) is provided with a protruding part (113) having a hole (114) extending in the direction in which the primary coil (61) and secondary coil (71) are disposed. The sensor (63) is provided in the hole (114).
