Abstract
A power supply unit capable of replacing a battery cell, including: a plurality of battery cells, each having an outer peripheral groove on one end side; a battery holder of an insulating material formed by disposing the battery cells at fixed positions; and a spring contact elastically pressed and electrically connected to positive and negative electrodes of the battery cell, in which the spring contact includes a first spring-contact formed by electrically connecting to an end-surface electrode, which is a first electrode of the battery cell, and a second spring-contact formed by electrically connecting to a second electrode of the battery cell, the battery holder includes an attachment / detachment recess part and a fitting claw, the first spring-contact is formed by electrically connecting to the end-surface electrode of the battery cell inserted into the attachment / detachment recess part, and the battery holder is formed by locking the fitting claw to the outer peripheral groove and disposing the battery cell at a fixed position in the attachment / detachment recess part in a state capable of pulling out the battery cell.
