Abstract
A sealed battery includes a battery outer case, a collector terminal, an outwardly exposed terminal, and a current shut-off mechanism configured to cut off a conductive path from the collector terminal to the outwardly exposed terminal when the internal pressure of the battery outer case exceeds a predetermined pressure. The current shut-off mechanism includes a connection plate with a vent hole, and a shut-off valve including a reversing portion. A joint region in the connection plate is in contact with a surface, of the reversing portion, that faces the inner side of the battery outer case. A thermal-spray joint portion configured to cover a border between the joint region and the reversing portion is provided, such that the shut-off valve is joined to the connection plate via the thermal-spray joint portion.
