In one embodiment, a nonaqueous electrolyte secondary battery includes an electrode group (32), a battery container (31), an insulation member (40, 41), and a nonaqueous electrolyte solution. The electrode group (32) includes a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode. The insulation member (40, 41), which insulates the positive electrode and the negative electrode from the battery container and absorbs vibration, includes a resin and an inorganic material and has a bending elastic modulus between 600 MPa and 1,500 MPa, a specific heat between 0.25 cal/°C·g and 0.40 cal/°C·g, and a thermal conductivity between 0.3 W/m·K and 0.6 W/m·K. |
