    Abstract: A sealed battery includes a battery can with a bottomed cylindrical shape having an opening, an electrode body accommodated in the battery can, and a sealing plate closing the opening of the battery can. The sealing plate has a first main surface facing an outside of the battery can and a second main surface opposite to the first main surface. The first main surface has a first groove therein with an arc shape. The second main surface has a second groove therein with an arc shape disposed to correspond to the first groove. The first groove has a central angle A1 smaller than a central angle A2 of the second groove. The first groove intersects a symmetry axis of the second groove on the second groove when viewed in a normal direction of the first main surface.
