Battery pack having electric insulating member

A battery pack comprising:

• two or more plate-shaped battery cells having anode terminals and cathode terminals formed at one sides thereof comprising sealed surplus portions, the battery cells being arranged in a plane such that the electrode terminals of the battery cells are aligned in one direction;
• a pack frame comprising two or more battery cell receiving parts surrounding outer circumferences of the battery cells in a state in which upper and lower surfaces of the battery cells arranged in the plane are opened;
• a protection circuit module (PCM) electrically connected to the electrode terminals of the battery cells aligned in one direction to control operation of the battery pack;
• a middle mold to receive the PCM, the middle mold being loaded on the sealed surplus portions;
• an electrically insulative member applied into a space defined by the sealed surplus portions and the pack frame and onto the middle mold and the PCM such that the middle mold and the PCM are integrated with the pack frame;
• and
• a label to cover the battery cells, the pack frame, and the electrically insulative member,
• wherein the pack frame is provided at at least one side thereof with one or more fastening parts protruding outward from the at least one side in a direction parallel to upper and lower surfaces of the battery cells.
