BATTERY PACK

PROBLEM TO BE SOLVED: To enable mass production at low costs by simplifying a packaging structure while preventing liquid leakage due to metallic corrosion. SOLUTION: The battery pack stores an electrode 2 and nonaqueous electrolyte in an exterior can blocking an opening by sealing plate 3. The sealing plate 3 is a plastic sealing plate made by molding plastic. The plastic sealing plate molds an external shape in a front surface side in a three-dimensional form to be set in an attaching portion 21 of electric apparatus 20, and the sealing plate airtightly blocking the exterior can and a member structuring a part of an outer case for specifying the external shape of the cell battery pack are made in an integral structure. The plastic sealing plate expresses on a front surface to fix an electrode terminal 8. The electrode terminal 8 is connected to a collector plate 9 fixed so as to express on the front surface of the sealing plate 3 through a collector base material 10. The collector plate 9 is connected to the electrode 2, and the electrode terminal 8 is connected to the electrode 2. COPYRIGHT: (C)2004,JPO
