CONSTITUTION:A base station 10 is provided with a power supply circuit 5 making a DC voltage constant from a power supply circuit 4 of an AC adaptor or the like and a circuit 11 driving a primary winding 12a. A mobile station 20 is provided with a secondary winding 12b arranged opposite to the primary winding 12a of the base station 10 and a rectifier circuit 13 rectifying an AC voltage generated in the secondary winding 12b into a DC voltage and supplying the result to a battery 3 via a charge current control resistor 7. When the mobile station 20 is placed on the base station 10, since the primary winding 12a of the base station 10 and the secondary winding 12b of the mobile station 20 are arranged opposite to each other, the AC voltage of the primary winding 12a and the secondary winding 12b is increased by the electromagnetic induction. Thus, the AC voltage of the secondary winding 12b is rectified by the rectifier circuit 13 to charge the battery 3.
