PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery having an excellent high-rate discharge characteristic. SOLUTION: In this nonaqueous electrolyte secondary battery, a positive electrode, a porous polymer electrolyte layer formed of polyvinylidene fluoride/ haxafluoropropylene copolymer, and a negative electrode are laminated, and the positive electrode and porous polymer electrolyte layer, and the negative electrode and porous polymer electrolyte layer are rigidly fixed. The nonaqueous electrolyte secondary battery is manufactured via a first process of assembling the nonaqueous electrolyte secondary battery, a second process of filling an electrolyte, and a third process of heating the battery at 100 deg.C or higher after sealing the battery. |
