Abstract

A secondary battery includes a reverse plate formed using a conductive material and provided in a case, and a fixing member formed using an elastically deformable material and joined to the reverse plate. When an internal pressure in the case is increased, the reverse plate deforms in response to the internal pressure, to thereby electrically connect a positive electrode terminal and a negative electrode terminal. With the increase in the internal pressure, the fixing member elastically deforms from a state where it is inserted into the through hole, exits the through hole and is fixed between the reverse plate and the case. The reverse plate in the deformed state is supported by the fixed fixing member.
