A battery pack includes a sealed case and a battery cell accommodated in the sealed case. The sealed case includes a case body, which has an opening, and a lid member, which is fixed to the case body by a plurality of bolts and closes the opening. When distances between adjacent ones of the bolts are compared, the distance between a specific adjacent pair of the bolts is greater than that between any other adjacent pair of the remaining bolts. |
