PROBLEM TO BE SOLVED: To reduce the number of retrial times when disposed with large inclination to a charger.SOLUTION: An electrode unit (1) includes: an electrode (10) and a plurality of first sensors (12) disposed mutually apart, for detecting that the charger contacts to or approaches the electrode unit (1). Further, the electrode unit includes: a slidable protection member (11) which, at non-charging of the battery, internally houses a tip of the electrode (10), whereas at battery charging, exposes the internally housed tip of the electrode (10); and a second sensor (13) which detects that the protection member (11) slides by a certain amount or greater.SELECTED DRAWING: Figure 1 |
