A nonaqueous electrolyte secondary battery includes an electrode body (20), a nonaqueous electrolytic solution, a battery case (80), and a bag-shaped film (10). The electrode body has a laminate structure in which a positive electrode (30) and a negative electrode (40) are laminated. The battery case accommodates the electrode body and the nonaqueous electrolytic solution. The bag-shaped film covers the electrode body to insulate the electrode body and an inner wall of the battery case from each other. An inner pressure of the battery case is adjusted to be 0.14 MPa to 0.23 MPa. |
