PURPOSE:To make the promotion of quantity production of the small size cell at low cost, by constructing an ion permeable portion in a part of the high molecular material sheet, and arranging a cell element with said portion being the separator, and making a coating with the high molecular material. CONSTITUTION:In a high molecular material sheet 1 not permeable for ion, are constructed a plurality of ion permeable parts 2, and with this part 2 used as the separator, is arranged the cell element of an anode active material 3, cathode active material 4, current collector rod 5, etc., and a high molecular coating material 6 and the high molecular material 1 are made adhesion and enclosed in a part other than the part 2. For the above described high molecular material sheet 1, it is preferable to use a polyolefine resin like polyethylene, polypropylene, etc. If required, the current collector may apply a construction with a current collecting protrusion 8 provided in a metalic plate 7, and this is penetrated to the active material, and can be cemented to the coating material 6 through a resin lining 9. |
