PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having a gas adsorbent exhibiting a high adsorption ability over a wide pressure range.SOLUTION: The nonaqueous electrolyte secondary battery includes an electrode group in which positive electrodes and negative electrodes are arranged with a separator interposed therebetween, a battery container for housing the electrode group, an insulation member for insulating between the positive and negative electrodes of the electrode group and the battery container, and a nonaqueous electrolyte for wetting the electrode group housed in the battery container. The insulation member contains a gas adsorbent having more than one maximum value in the range of 0.2-1.5 nm of pore size distribution. |
