Abstract:
1. A battery pack which is used in a status being mounted on electronic equipment, a battery being built in a case and an output terminal electrically connected to the battery, the output terminal being mounted in such a manner as to be directed towards the outside of said case, wherein said case comprises a main body having an approximately rectangular box shape with said battery built therein, and an output section having said output terminal formed on one plane of said main body, said main body comprises: a mount reference plane of the case for the electronic equipment; an opposing surface opposing the mount reference plane; a pair of first side surfaces respectively opposing each other and respectively substantially perpendicular to the mount reference plane and the opposing surface; and a pair of second side surfaces respectively opposing each other and respectively substantially perpendicular to the mount reference plane and the opposing surface, wherein said opposing surface is gradually curved from at least one surface of said pair of first side surfaces, in a direction to deviate from said mount reference plane as said opposing surface reaches a central portion between the pair of first side surfaces, wherein said output section is formed in a projecting manner on a surface of one of said pair of second side surfaces of said main body in a position deviated towards one corner formed by said first side surfaces adjoining the second side surfaces and in a position spaced apart into a direction orthogonal to a virtual plane including said mount reference plane, wherein an engagement for engaging said electronic equipment is formed on one surface where said output section is formed, of said pair of second side surfaces, and in the central portion between said pair of first side surfaces, and on said one surface where said output section is formed, of said pair of second side surfaces, in the central portion between said pair of first side surfaces, and on the verge of said opposing surface, an ejection-purpose fingerhold which projects from the second side surfaces and aligned with said output section formed in projecting manner on the second side surfaces is provided.
