PROBLEM TO BE SOLVED: To easily perform attachment/detachment and to improve reliability in fitting when attachably and detachably fitting a battery pack onto a rear face of a video camera directly without putting the battery pack into a battery case. SOLUTION: A battery pack 11 mounted detachably from a video camera 1 comprises a convex side member 132 detachably coupled from the upside to a concave side member 131 on a rear face 2d of the video camera, and a concave portion 133 formed at a position corresponding to the concave side member 132 when the convex side member 132 is coupled with the concave side member 131. When coupling the convex side member 132 with the concave side member 131, the convex side member 132 and the concave side member 131 are coupled in a relation between dovetail and dovetail groove and the convex side member 132 is inserted into the concave side member 131, so that the video camera 1 and the battery pack 11 are coupled so that their coupling faces may be brought into contact.
