Abstract
A battery includes: an electricity-generating element; an exterior; an external terminal member; a current-collecting terminal member having a first end which is connected to the electricity-generating element and a second end, which extends outward of the exterior; and a platy connection member that, outside the exterior, interconnects the current-collecting terminal member and external terminal member. In the welding between the connection member and an outer peripheral side end portion of a swaged portion in which the second end of the current-collecting terminal member has been swaged toward an insertion hole of the connection member, an acute angle between a connecting line connecting the weld portion to a center of the second end and a longitudinally extending center line of the lid member is greater than or equal to 45 degrees. A production method for the battery and a battery production-purposed mask are also provided.
