Abstract: A prismatic battery with highly reliable sealing properties and its manufacturing method, wherein a negative collector is welded to one end of an electrode plate group accommodated in a prismatic case, the collector being connected to an electrode pole that functions as the negative electrode terminal, and the electrode pole is fitted into a support cylinder that is provided on an upper lid for closing one open end of the case. An insulating gasket is interposed between an inner periphery of the support cylinder and an outer periphery of the electrode pole, the support cylinder being formed with at least one annular crimped portion that has an arc-shaped longitudinal cross section.
