Provided is a secondary battery which has improved the adhesive strength of a resin molding part and prevents a resin molding part from being twisted by improving the structure of a gasket. A secondary battery(100) comprises a jelly-roll type electrode assembly which comprises a positive electrode plate, a negative electrode plate, and a separator for insulating the two electrode plates; a can(120) in which the electrode assembly is accommodated; a bare cell(110) which is provided with a cap assembly(130) comprising a cap plate(131) for sealing the upper aperture of the can and an electrode terminal with a gasket(133) inserted into the terminal penetration hole of the cap plate; and a protection circuit board(150) which is combined to the upper part of the bare cell by a resin molding part, wherein a stopper(133a) is projected at the gasket to combine the resin molding part with the bare cell. |
