In a nonaqueous secondary battery including a pressure-operated current interrupt device, a ratio (Vt/Cr) of a sum Vt (cm3) of an effective pore volume Vp of the positive electrode active material layer, an effective pore volume Vn of the negative electrode active material layer, and a pore volume Vs of the separator to a volume Cr (cm3) of a remaining space in the battery case is 0.92 to 1.05. The volume Cr of the remaining space in the battery case is calculated by subtracting a volume Ce of the electrode body, a volume Cna of the nonaqueous electrolytic solution, and a volume Cc of auxiliary components from a volume Ct of the battery case. The remaining space volume Cr (cm3) is 14.8 vol % or higher of the volume Ct (cm3) of the battery case.
