PROBLEM TO BE SOLVED: To provide an effective manufacturing method of a thin cell with high energy density and excellent cycle characteristics. SOLUTION: For the thin cell comprising the first and the second electrode plates 1, 2 as a positive electrode and a negative electrode respectively, and a porous separator 3, the electrode plates and the separator are stacked and wound around a core 4. Afterwards, the core is removed by arranging the separator 3 at both side of the first electrode plate interposing a thermoplastic resin, a thermoplastic layer at both side of the second electrode plate is formed, and a laminated body, composed of the first electrode plate and the separator, is wound so that is locates at the position between the second electrode plate and the core. |
