PROBLEM TO BE SOLVED: To provide a manufacturing method for a nonaqueous electrolyte secondary battery, having a porous polymer electrolyte with improvel high rate discharge performance and cycle performance. SOLUTION: This nonaqueous electrolyte secondary battery has the porous polymer electrolyte between a positive electrode and a negative electrode, the porous polymer electrolyte contains a first polymer electrolyte and a second polymer electrolyte, having different melting points, and satisfies the relation T1<T2, when the melting point of the first polymer electrolyte is represented by T1( deg.C) and that of the second polymer electrolyte is represented by T2( deg.C). |
