A secondary battery is provided to improve the bonding strength of a resin molding unit forming appearance and connecting a protection circuit board at the upper part of by improving a structure of a sealing member, and to prevent the twisting of the resin molding unit on the basis of a bare cell. A secondary battery(100) comprises a bare cell(110) and a protection circuit board(150) connected by a resin molding unit which is molding resin on the top of the bare cell. The bare cell comprises an electrode assembly(122) in which a positive plate, a negative plate and a separator insulating the positive plate and the negative plate are wound in order; a can(120) accommodating the electrode assembly; and a cap assembly containing a sealing member(137) sealing a cap plate(131) and an electrolyte inlet(131b). The sealing member comprises a sealing part sealing the electrolyte inlet and a stopper part restricting the resin molding unit. |
