Abstract
A positive electrode plate, a separator, and a negative electrode plateare prepared. The positive electrode plate, the separator, and the negative electrode plateare combined so as to form a spirally-wound electrode assembly. A winding end portionof the electrode assemblyis fixed with a heat-sensitive adhesive (preferably, a heat-sensitive adhesive tape) whose adhesive force can be reduced by heating or cooling. The electrode assemblyis placed in an outer casing, and then the ambient temperature of the electrode assemblyis adjusted so that the electrode assemblyis loosened due to reduction in the adhesive force of the heat-sensitive adhesive. An electrolyte solution is injected into the outer casing
