  With the above configuration, the primary coil 3 and the secondary coil 4 form a separate detachable transformer 5, and if the electric shaver holder 17 is energized from the power source 6 in the holding state, the high-frequency generated in the primary coil 3 is reduced. The primary coil 3 and the secondary coil 4 are magnetically coupled by the alternating magnetic flux 9, and at this time, an electromotive force is generated in the secondary coil 4 to feed or charge the secondary battery 11. The charging function is a main function performed in a non-contact state in the holding state.
