A current path cut-off component of a cell is to be provided which is smaller in the number of parts used than in conventional like components and which is superior in assembling performance. In the current path cut-off component of a cell according to the present invention, a current path is formed between a cell lid and a power generating element (not shown) disposed in the interior of the cell, through a diaphragm portion and a lead, the diaphragm portion displaces itself upon an increase in internal pressure of a cell case above a predetermined value, and this displacement of the diaphragm portion causes the diaphragm portion and the lead to be separated from each other to cut off the current path.
