Abstract:
A battery case lid is formed by working a metal plate, and includes a substrate section and an explosion-proof valve formed in the substrate section. The explosion-proof valve has a reduced thickness section that is thinner than the substrate section, and the reduced thickness section is formed by extending the metal plate by applying pressure while the metal plate is kept unrestrained.
