Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a proximity wireless charging AC adapter shared among portable devices capable of gaining relatively high power transmission efficiency while avoiding an impact on the operation of the portable devices by means of magnetism loose coupling.SOLUTION: A proximity wireless charging AC adapter 24 includes: a first diode bridge 2 connected to an AC terminal; a chopper control part 4 connected to the first diode bridge 2: a primary side resonance capacity C1 connected to the chopper control part 4; a primary side coil 10 connected to the primary side resonance capacity C1 for synchronizing with the primary side resonance capacity C1 in a prescribed electric power carrier wave frequency band; a secondary side coil 12 contained in a portable device 30; and a secondary side resonance capacity C2 connected to the secondary side coil 12 for synchronizing in a prescribed electric power carrier wave frequency band. By allowing the primary side coil 10 to synchronize with the secondary side coil 12 in a prescribed electric power carrier wave frequency band, the proximity wireless charging AC adapter 24 decreases the dynamic impedance and charges portable devices in non-contact due to the magnetism loose coupling.
