Abstract
In a current cutoff mechanism for a cell, when the internal pressure of a cell case exceeds a predetermined value, a diaphragm section is displaced upward, and a terminal is broken from portions of a V-shaped groove section in contact with two slits, thereby cutting off the current path formed between a cell lid and a power generating element inside the cell.
