A wireless power transmission system (401) which transmits power from a power transmission device (101) to a relay power receiving device (201) by applying a voltage to an active electrode (11) in the power transmission device (101) facing an active electrode (21) in the relay power receiving device (201) and a passive electrode (12) in the power transmission device (101) facing a passive electrode (23) in the relay power receiving device (201), wherein the relay power receiving device (201) includes an active electrode (22) connected to the active electrode (21) and a passive electrode (24) connected to the passive electrode (23). A power receiving device (301) includes an active electrode (31) facing the active electrode (21) and a passive electrode (32) facing the passive electrode (24) and supplies a load with a voltage induced by the active electrode (31) and the passive electrode (32). Thereby, it is possible to provide an electronic device and a power transmission system capable of transmitting received power to another device without reducing the transmission efficiency. |
