A secondary battery includes a unit cell including an electrode assembly provided with a tab bundle and having a round portion, and a cap member in the vicinity of the round portion of the electrode assembly. The cap member includes a pair of first surfaces which are parallel to an upper surface and a lower surface of the electrode assembly, a pair of second surfaces which are parallel to both side surfaces of the electrode assembly, one third surface which connects the pair of first surfaces and the pair of second surfaces, and a contact member provided in an internal space formed by the pair of first surfaces, the pair of second surfaces, and the one third surface and in contact with the round portion of the electrode assembly. The third surface is provided with a through hole through which the tab bundle passes.
