Abstract
A method for manufacturing a sealed battery according to one embodiment of this invention includes a first step of using an outer canhaving an opening, and a sealing platehaving a flange provided with a groovearound or on a part of a fitting face of the sealing platewith the outer can, and inserting the sealing plateinto the opening of the outer canso that a top face of the outer canis approximately flush with a top face of the flange of the sealing plate, and a second step of welding together the outer canand the sealing plateby radiating a high energy ray to the fitting portion therebetween. The invention thus makes it possible to provide a method for manufacturing a sealed battery in which a weld formed by welding a sealing plate fitted into an opening of an outer can of a battery with a laser or other high energy rays has a large breaking strength, and a sealed battery manufactured thereby.
