PROBLEM TO BE SOLVED: To provide a means enabling improvement of a shock-resistant performance of a battery pack used for electronic equipment. SOLUTION: The battery pack is provided with a plurality of cylindrical battery cells 8 arrayed in a plurality of rows and plurality of steps, partitioning members 20 partitioning the battery cells 8, and an outer case 2 housing the battery cells 8 partitioned by the partitioning members 20. By forming a thickness of the outer case 2 thicker than that of the partitioning member 20, strength of the outer case 20 can be improved to achieve improvement in a shock-resistant performance.
