Abstract
The invention provides a closed type battery comprising an electrode-leading terminal formed by caulking that ensures satisfactory sealing sealability. That terminal comprising a metal plate for sealing up an opening in a battery can, an insulating member that cover a through-hole provided through the metal plate and both surfaces of the metal plate around the through-hole, an electrode-drawing sheet positioned on a surface of the insulating member located on an outer surface of a battery and an electrode-leading pin that is inserted into the through-hole in the electrode-drawing sheet and caulked from above and below. At the surface of contact of a flange of the electrode-leading pin with the insulating member there is provided at least a projection.
