PROBLEM TO BE SOLVED: To provide an oblong nonaqueous electrolyte battery using light metal as an anode activator, housing a power generation element housed in a battery case serving as a cathode terminal, which solves the problems caused by scatter and lowering of strength of calking. SOLUTION: The oblong battery housing the power generating element comprises a bottomed cylinder-shaped battery case serving as the cathode terminal; an anode having light metal as an activator; a current collection rod, around which a separator is wound, serving as an anode terminal; and a gasket sealing an opening of the battery case, holding the current collection rod and the battery case, insulating them from each other. The battery case is formed by applying a drawing process or a DI process on a clad metal plate of either a stainless steel, a nickel plated steel, or a nickel plate, with an aluminum plate so that the aluminum plate be on an inner face side, and a ratio of the thickness of the aluminum layer at the side face of the battery case to the thickness of the battery case is made not less than 20% and less than 50%.
