<P>PROBLEM TO BE SOLVED: To provide a battery pack capable of enhancing its reliability by lowering the height of a coupled solder portion when at least two unit cells are coupled in series or parallel with a protection circuit module. <P>SOLUTION: The battery pack comprises a unit cell including a bare cell, an electrode tab extended from the bare cell, a circuit board connected electrically with the electrode tab and a conductive lead projecting from the bare cell and connected electrically with the circuit board. The conductive lead includes a base coupled with the circuit board, and an inserting portion projecting from the base and having a recess or a through hole. The inserting portion projects from the base to pass through an open portion of a protection circuit module including an insulating substrate having the opening portion formed in correspondence with the unit cell. <P>COPYRIGHT: (C)2012,JPO&INPIT |
