The battery pack charger has a case 1 having an attachment section 2 where the battery pack 30 is attached in a detachable manner, and a plurality of connecting terminals 3 disposed in an exposed manner in the attachment section 2 to connect with external terminals 33 on the battery pack 30. The connecting terminals 3 are disposed in approximately vertical orientation in a plurality of approximately parallel rows. The case 1 has terminal through-holes 52 opened through the case 1 between adjacent connecting terminals 3. Even if there is ingress of foreign material such as dust and dirt between the connecting terminals, that material can fall through the holes in the case. Foreign material collection between the connecting terminals can be avoided, and the battery pack charger has the positive feature that unintended conduction such as leakage current and short-circuit can be avoided.
