る密閉電池。In a sealed battery, in which at least one electrode terminal part is attached to a synthetic resin sealing plate that seals the opening of a battery case containing a power generation element, a pair of concave rivets and a convex rivet are used as the electrode terminal part constituent members, and the sealing plate is sealed. Insert the concave rivet into the through hole of the plate from one side, insert the convex rivet from the other side, and press the sealing plate outward in the radial direction to create a tight seal between the sealing plate and the concave rivet. A sealed battery characterized by ensuring the following.
