Abstract: A cylindrical cell is disclosed which is so constructed that an insulating ring is seated on the outside of the sealed part of the opening part of a cell case, the terminal face of a negative electrode plate is depressed below the outer face of a facing label covering the insulating ring, and a gas discharge hole formed in the negative electrode plate is concealed with the insulating ring. This construction prevents the cell from allowing flow of a current to an adjacent cell and consequently from being charged by the adjacent cell. Since the cell uses a thermally shrinkable insulating facing member, it enjoys improved reliability of the outer covering.
