<P>PROBLEM TO BE SOLVED: To provide a flat battery having a structure strong against an imposed external force. <P>SOLUTION: The flat battery having a terminal led out from an end edge of an outer periphery is constituted of two sheets of positive electrode plates 101 coated with a positive electrode active material, five separators 102 of micro-porous films, two sheets of negative electrode plates 103 coated with a negative electrode active material, positive electrode terminals 104 connected to each positive electrode plate 101, negative electrode terminals 105 connected to each negative electrode plate, an electrolyte not illustrated, and an upper part cell outer packaging member 106 and a lower part cell outer packaging member 107 to seal these above. The cell outer packaging members 106, 107 are constituted of a first resin layer located in the innermost layer, a second resin layer located in the outermost layer, and a metal layer pinched by those two layers and laminated, the first resin layer having a smaller Young's modulus than the second resin layer. <P>COPYRIGHT: (C)2004,JPO |
