PROBLEM TO BE SOLVED: To simplify the assembly process while improving the current collecting effect. SOLUTION: In this method, a positive electrode can 12 fixing a positive electrode active material 11, and a negative electrode can 14 fixing a negative electrode active material 13, are fitted to hold a separator 15 between them, after an electrolyte solution is filled to either one can 12 or 14. Furthermore, the fitting part of the positive electrode can 12 and the negative electrode can 14 is sealed airtight, a collector 16 which consists of numerous short fibers which have conductivity and magnetism, and do not react with the above electrolyte solution is welded on the inner bottom surface of the positive electrode can 12 and/or the negative electrode can 14, and the positive electrode active material 11 or the negative electrode active material 13 is put into and fixed to this collector 16. |
