摘要： Provided is a cylindrical secondary battery including a cylindrical exterior can having an open top portion into which an electrode assembly and electrolyte can be inserted and having an electrode tap which is drawn from the electrode assembly and extends upward; and a cap assembly assembled as an integrated structure, having an outer side surface welded and fixed to an inner side surface of an upper portion of the exterior can, and having a bottom surface joined and electrically connected to the electrode tap to transmit electric current generated by the electrode assembly to the outside. In addition, provided is a method of manufacturing a cylindrical secondary battery. The method includes assembling a cap assembly as an integrated structure; inserting an electrode assembly and electrolyte into a cylindrical exterior can having an open top portion; joining and electrically connecting an electrode tap, which is drawn from the electrode assembly, to a bottom surface of the cap assembly; inserting the cap assembly into the open top portion of the exterior can and thus bending the electrode tap; and welding an outer side surface of the cap assembly to an inner side surface of an upper portion of the exterior can.
