PROBLEM TO BE SOLVED: To provide a wireless power distribution system that can surely monitor abnormalities of the system. SOLUTION: An electric field intensity sensor 6 is provided in an indoor space 1. A detected value RPW of the level of electromagnetic waves from a wireless power supplying apparatus 2 (detected value of the level of received electromagnetic waves) detected by the electric field strength sensor 6 is sent to an external controller 5. A distribution level LPW/HPW determined by a system control section 2B of the wireless power supplying apparatus 2 (the set value of the level of transmitted electromagnetic waves) is sent to the external controller 5. The external controller 5 diagnoses abnormality of the system, based on the set value LPW/HPW of the level of transmitted electromagnetic waves and the detected value RPW of the level of received electromagnetic waves. For example, when a difference between the set value LPW/HPW of the level of transmitted electromagnetic waves and the detected value RPW of the level of received electromagnetic waves is out of a predetermined range, it is determined that there is an abnormality in the system. Likewise, a system abnormality could be diagnosed by the system control section 2B of the wireless power supplying apparatus 2. COPYRIGHT: (C)2011,JPO&INPIT
