WINDING-TYPE BATTERY, AND MANUFACTURING METHOD FOR POWER GENERATION BODY OF WINDING-TYPE BATTERY

PROBLEM TO BE SOLVED: To provide a winding-type battery capable of attaining good battery performance since a separator is fixed on a core material without using an adhesive tape and an adhesive agent which give bad effect on battery performance and the separator and an electrode plate are properly wound around the core material. SOLUTION: In the winding-type battery having the core material, two electrode plates used as a positive electrode and a negative electrode, and the separator and having a power generation body wound around the core material while the electrode plate and the separator are alternately arranged, a sheet extended at a designated length in a peripheral direction from an outer periphery of the core material is provided, and the separator is wound while one end of the separator is interposed between the core material and the sheet.
