<p>PURPOSE: A battery pack is provided to simplify a manufacturing process and a structure by mounting an electrical element on a protection circuit module with a COB(chip on board) mode and forming a resin layer. CONSTITUTION: A battery pack(100) comprises a bare cell(110) formed by sealing a can accommodating an electrode assembly and a cap assembly; a protection circuit module(120); and a cover case(130) which protects the protection circuit module and is combined with the bare cell. The protection circuit module comprises an insulating board(121), an electrical device installed with a COB mode on one side of the insulating board, and a resin layer(125) surrounding the electrical device.</p> |
