摘要：
A sealing structure (10a) for a lithium ion battery (10) includes a metal lid (2), a polymer molding (3), and an electrode (11). A back surface (2c) of the metal lid (2) has an annular first projection (51) around a through hole (2a) of the metal lid (2). A front surface (11c) of a plate portion (11b) of the electrode (11) has an annular second projection (52) around the through hole (2a). Values α and β expressed by the following formula (1) satisfy a predetermined relation, where h1 and h2 respectively represent the heights of the first and second projections (51) and (52), d represents the distance between the first and second projections (51) and (52), and H represents the thickness of the base portion (3b) of the polymer molding (3). α = h 1 + h 2 / H , β =d/H
