Abstract
In order to provide a battery capable of simultaneously mounting and using plural batteries without requiring the extra structure body such as a box-shaped holder, the center portion of a rear cover 10 constructing the battery is recessed and on the top of its recess part 15, a substantially V-shaped fitting plate 16 with a dovetail shape for mounting by a fitting structure of a dovetail joint to an adapter plate mounted in a video camera is fixed. In a top cover 11, portions substantially corresponding to the recess part 15 of the rear cover 10 are protruded, and a substantially V-shaped recess groove 22a with a shape in which protrusion parts 22, 22 correspond to the fitting plate 16 is formed.
