To provide a charging table without generating a short circuit accident, even if foreign matter invades from a terminal hole 1b, by arranging a partition wall 6a between battery connection terminals 7.

In a battery charger, three battery connection terminals 7 provided with terminal holes 1b at three portions passing through outer packaging cases 1 and 2 on a mounting part 1a provided on the outer packaging case 1 to mount a battery pack and connected to a circuit board 3 at the inside of the outer packaging cases 1 and 2 are provided to be supported by terminal bases 6 mounted on the circuit board 3 for supporting parts 7a and to project a contact part 7b to the mounting part 1a by elasticity through the terminal hole 1b. The partition wall 6a is arranged between each battery connection terminal 7 at the inside of the outer packaging cases 1 and 2.
