CONSTITUTION: A battery pack(90) comprises a battery cell(91), a case(92) accepting the battery cell, and an adhesive sheet(900) surrounding at least a part of an outside the case. The adhesive sheet comprises a substrate part(910) comprising a cut line(911) arranged in a position corresponding with the edge of the case, and an adhesive part(920), which is arranged on the bottom of the substrate part, comprising air drain holes. The cut line is formed on the top of the substrate. A depth of the cut line is lower than a thickness of the substrate part. |
