Abstract: A sealing body of a battery includes a positive electrode cap, a safety valve electrically connected to the positive electrode cap, a plurality of protrusions that are disposed annularly and intermittently on the outer peripheral side of a conductive contact part of the safety valve and that are each formed so as to be inclined toward the center of the sealing body, and an insulating member that covers at least top parts of the plurality of protrusions, side surfaces thereof on the center side, and a surface of the safety valve on the center side, that is fitted to the center side of the plurality of protrusions, whose vertical sectional shape is bent in a Z-shape. A terminal plate is fitted and fixed to the center side of the insulating member and is connected by welding to the conductive contact portion through a central opening of the insulating member.
