Abstract

A lid of a rechargeable battery includes a lid body that closes an opening of a case body and is supported by a case-side mating surface surrounding the opening of the case body. The lid also includes an inserted portion having a shape of a quadrangular column. The inserted portion protrudes from the lid body toward an inner part of the case body and extends along an inner circumferential surface of the case body. The lid also includes a rounded corner present in the distal end of the inserted portion in a protruding direction in which the inserted portion protrudes from the lid body. The lower limit of an edge-removal dimension of the corner is equal to an average particle diameter of a material for the lid.
