Provided is a battery pack to allow the electrolyte solution of a bare cell to be discharged to other position in case of the leakage of the electrolyte solution to the circuit board of the upper part of a separator. The battery pack comprises at least one bare cell; a separator(120) of a certain width which is located on the upper surface of the at least one bare cell; and a circuit board which is installed on the separator and is connected to the bare cell by a conducting wire, wherein a slope(121a) is formed on the separator to allow electrolyte solution to flow rapidly in a certain direction when the electrolyte solution of a cell intrudes the circuit board of the upper part of the separator, and at least one discharge hole(124) is formed at the end part of the slope to allow the electrolyte solution to be discharged to the bare cell part. |
