Abstract
According to one embodiment, a battery includes a flat-shaped electrode group, a package member and a terminal section. The package member includes a stainless steel-made first package having a flange at an opening and a stainless steel-made second package. The electrode group is stored in a space formed by welding the flange of the first package to the second package. The terminal section includes a through-hole that is open to the first package, a ring-shaped rising portion that extends from a periphery of the through-hole toward an inside of the package member, a ring-shaped member that is arranged on an outer surface of the rising portion, an insulation gasket, and an external terminal. The external terminal is fixed to the first package by caulking.
