  • Patent number: 6977125
    Abstract: The present invention provides a closed type battery that is free from any sealing defects due to a sag of caulking with time, etc. The closed type battery is constructed of a monolithic electrode terminal that comprises an insulating member for covering the inner surface of a through-hole formed through a metal sheet for sealing up an opening of a battery can and both surfaces of the metal sheet around the through-hole, and an electrode-drawing sheet having a synthetic resin layer formed on one surface thereof, which sheet is located on the surface of the insulating member positioned on the outer surface of the battery while the synthetic resin layer comes in contact therewith, wherein the electrode-drawing sheet and the insulating member are integrated together by means of an electrode-leading pin passed through a through-hole in the electrode-drawing sheet.
