A secondary battery pack is provided to reduce the number of parts and work process, to ensure a stable coupling structure capable of minimizing the defectives caused by external shock and the change of internal resistance. A secondary battery pack(100) includes a battery cell(200) where an electrode assembly is sealed up with electrolyte inside the battery case; an insulating mounting member(400) which has an opening(410) for exposure of an electrode terminal(220), mounts a protection circuit module assembly, and is mounted on the top(210) of the battery cell; a protection circuit module assembly(300) attached in a structure being exposed via through-holes(310,320); a PTC element(600) which is located on an electrical contact circuit of the protection circuit module assembly and the battery cell; and an insulating cap(500) attached to the upper part of the battery cell while surrounding the insulating mounting member when the protection circuit module assembly is mounted. |
