Abstract
A protection module capable of being utilized by a secondary battery regardless of the external mounting structure of the secondary battery for mounting the secondary battery to an external device. Accordingly, it is unnecessary to separately manufacture a protective circuit module according to the external mounting structure of the battery. The secondary battery includes: a plurality of bare cells each of which includes a can, an electrode assembly, and a cap assembly; a first protective circuit module located on the upper surface of the bare cells that is formed by the cap assemblies; and a secondary protective circuit module located on a side surface of the bare cells that is formed by curved surfaces of the cans. The first protective circuit module and the second protective circuit module are electrically connected to each other.
