及び小型化、コストの低減化が可能となる。As described above, the charging device according to the present invention includes the charging current supply terminal and the battery detection terminal in order to start charging by detecting that the secondary battery to be charged is mounted at a predetermined position,
When the secondary battery is mounted, the charging current supply terminal which is in contact with the electrode of the mounted secondary battery is pressed by the secondary battery and thereby comes into contact with the battery detection terminal, thereby obtaining a charging start signal. This eliminates the need for a dedicated detection switch provided for detecting battery installation as in the conventional case, and merely provides a detection terminal formed of the same material as the supply terminal. And the battery can be reliably detected even in a state where there is a margin in the mounting accuracy between the mounting detection member and the battery, and it is possible to increase the reliability, reduce the size, and reduce the cost of the charging device.
