PROBLEM TO BE SOLVED: To securely regulate a battery pack so as not to be mounted on a battery mounting device in an inclined state. SOLUTION: This battery pack includes a battery cell, a case 19 for storing the battery cell, first, second and third output terminals 21, 22, 23 for outputting power of the battery cell, a bottom surface 24 of the case 19 linked to a front surface 20 of the case 19 having each of the output terminals 21, 22, 23 and arranged approximately vertically to the front surface 20, a recessed part 30 for identification provided on an approximately center line of the bottom surface 24 orthogonal to the front surface 20, regulating recessed parts 28, 29 for engaging with a first battery mounting device formed on a corner part of the front surface 20 and the bottom surface 24 by opening on the front surface 20 and the bottom surface 24. The regulating recessed parts 28, 29 are formed in a folding shape so that an opening of the front surface 20 has a part orthogonal to the bottom surface 24 and a part parallel to the bottom surface 24. |
