<P>PROBLEM TO BE SOLVED: To provide a thin-film primary battery capable of avoiding the degradation of the battery characteristics by improving the bending characteristics. <P>SOLUTION: A lithium primary battery 10 includes an electrode laminate 11 comprising a positive electrode 21 supported by a positive electrode collector 23, a negative electrode 31 supported by a negative electrode collector 33, laminated with a separator 41 interposed therebetween. The electrode laminate 11 together with an electrolyte are encased in a case 51 made of laminated films 53 to be hermetically sealed. The positive electrode collector 23 is made of stainless-steel foil, and the stainless-steel foil at the outermost layer of the electrode laminate 11 is welded to the inner surface of the laminated film 53 via a thermoplastic resin 55. <P>COPYRIGHT: (C)2013,JPO&INPIT |
