Abstract
If a non-aqueous electrolyte secondary battery has a seal structure between a lid and an electrode terminal in which a seal member is compressed by fastening a nut, the nut may be loosened to make the amount of compression of the seal member insufficient to reduce the seal performance even if the nut is fastened enough to obtain an appropriate amount of compression of the seal member at the time of manufacture of the battery. A battery case has an opening, and houses an electrode group and an organic electrolyte. A lid is fastened to the battery case, and tightly seals the opening of the battery case. An electrode terminal is electrically connected to the electrode group. The lid and the electrode terminal face each other via an elastic member.
