BATTERY PACK OF NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

PROBLEM TO BE SOLVED: To make the whole structure simple, and to improve reliability when falling down or the like. SOLUTION: The cell battery pack of a nonaqueous electrolyte secondary battery stores an electrode 2 and a nonaqueous electrolytic solution in a case airtightly blocking a can bottom of a main body portion 1A by a bottom cover 1B, and its external shape is molded in a three-dimensional form to be dettachably attached to an attaching portion 21 of electric apparatus 20. The battery pack puts the electrode 2 in a plastic case 1 wherein at least an inner surface and a front surface are made by plastic. The plastic case 1 has an external shape that is a three-dimensional form set to attached/detached to/from the attaching portion 21 of the electric apparatus 20, and an internal shape storing the electrode 2. The plastic case 1 makes an exterior can of the battery for storing the electrode 2 and electrolyte and an outer case specifying the external shape of the battery pack become an integral structure, and the bottom cover 1B is molded by plastic material superior to that of the main body portion 1A in shock absorbing performance.
