PROBLEM TO BE SOLVED: To aim at improvement of safety and discharging characteristics of a nonaqueous electrolyte secondary battery. SOLUTION: With the nonaqueous electrolyte secondary battery provided with positive electrode combined agent layers 15 including positive electrode active material 15 and negative electrode combined agent layers 19 including negative electrode active material and provided with a porous polymer film 5 between each positive electrode combined agent layer 15 and the negative electrode combined agent layer 19, at least either the positive electrode combined agent layer 15 or the negative electrode combined agent layer 19 is structured to include inorganic solid electrolyte powder. Further, a porous polymer can be contained in at least either the positive electrode combined agent layer 15 or the negative electrode combined agent layer 19. Inorganic solid electrolyte can be contained in the porous polymer film 5 between the positive electrode combined agent layer 15 and the negative electrode combined agent layer 19.
