There is a possibility that a charging current necessary for charging the secondary side charging coil 5 will not be generated. Therefore, in the present invention, the mountain-shaped projection 12 is formed substantially at the center of the storage section 11 as described above. Therefore, the bottom of the electric toothbrush 1 inserted into the charging stand 1 is located around the storage section 11 so as to be guided by the mountain-shaped projection 12. In other words, the secondary charging coil 5 of the electric toothbrush 1 is located near the primary charging coil 13, that is, in a region where the magnetic flux density of the high-frequency magnetic field generated by the primary charging coil 13 is sufficiently strong. This means that the secondary side charging coil 5
Generates a sufficient charging current.
