In the non-aqueous electrolyte cell, electric generation elements are housed in a bottomed-cylindrical outer casing can, the end portion at the opening side of the bottomed-cylindrical outer casing can is crimp-sealed via a gasket, one end of a current output terminal is connected to either one of the positive and negative electrodes, which are electric generation elements, and the other end of the current output terminal protrudes outside the cell through the opening of the bottomed-cylindrical outer casing can. The current output terminal has a flange portion and a tapering corner portion formed on the lower surface of the flange portion. Both surfaces of the flange portion are in touch with the gasket, and the crimping is made to a portion below the flange portion.
