A non-aqueous electrolyte cell having high hermetic sealing and hermetic sealing properties and which is reduced in thickness. A unit cell of the non-aqueous electrolyte cell (1) is accommodated in a packaging material formed by a laminated film (2). The packaging material includes at least a metal layer and a heat fused layer arranged on an inner side of the metal layer. The heat fused layer is made up of aplurality of layers each containing the same monomeric unit. A mixed layer where plastic materials of the plural layers co-exist is formed between the plural layers such that the heat fused layer is in the form of a continuous film not having a definite boundary surface. <IMAGE> |
