PROBLEM TO BE SOLVED: To suppress heating of a blade edge by providing a booster circuit in the preceding stage of an electromagnetic induction heating circuit and optimizing respective conversion power when triggering and driving them by a common oscillation circuit when drying the blade tip by electromagnetic induction heating in a shaver system capable of supplying power to a shaver and a washing device by the same DC voltage by changing an AC adapter. SOLUTION: DC 5V to be shared with the shaver is inputted from the terminal 3a of the AC adapter 3 to the booster circuit 7 of the washing device, and by turning an FET Q1 ON/OFF by the oscillation circuit OS1, boosting is performed using a choke coil L2, and with the DC 24 V of a boosted result outputted from a capacitor C1 as a power source, the electromagnetic induction heating circuit 18 turns the power of a coil L1 on/off by an FET Q2 and inductively heats the blade edge of the shaver. At the time, by supplying the trigger pulse of the oscillation circuit OS1 through an inverter INV to the FET Q2, a high duty for boosting and a low duty for heating are attained.
