<p>A secondary battery having improved quality can be manufactured in a simplified manner by automating a soldering process required to electrically connect an external terminal provided in a case of the secondary battery with a PCM. The secondary battery includes a bare cell, a PCM coupled to an upper portion of the bare cell, and a casing coupled to the PCM and the upper portion of the bare cell, wherein a solder for coupling the casing to the PCM is formed on a bottom surface of a PCB forming the PCM, and a melting point of the solder is lower than a softening point of the casing.</p> |
