摘要： An alkaline storage battery includes: a cylindrical case having a side wall including an opening end portion and a bottom; a sealing plate; a gasket interposed between the sealing plate and the opening end portion; and a sealant between the gasket and the opening end portion. The side wall has an annular groove opened at an outer surface thereof, and an inwardly curl portion at the opening end portion. In at least part of the groove, the minimum width L1 is within 0.2 mm. The sealant includes a polyamide resin formed such that when two test-plate materials are bonded together at bonding faces facing each other via a bonding portion of the sealant, and moved in parallel with the bonding faces and in opposite directions to have a relative displacement within 0.5 to 5 mm, a stress at least 0.02 N/mm2 is applied to the bonding portion.
