PROBLEM TO BE SOLVED: To easily take out an incorporated component. SOLUTION: An opening for permitting taking-out a secondary battery 14 from an outer part includes a seat surface 12 which is smaller than the opening. The seat surface 12 is connected to a case body with ribs 28a-28d. Slits 12a-12d are arranged between the seat surface 12 and the case body. When the ribs 28a-28d are cut, the seat surface 12 is removed. The secondary battery 14 is exposed outward so as to be easily taken out. COPYRIGHT: (C)2007,JPO&INPIT
