1. A battery pack comprising:
a pack case having a receiving portion;
a plurality of battery cells which are oriented in a first direction and are accommodated in the receiving portion of the pack case; and
a reinforcing pole for reinforcing mechanical strength of an inside of the pack case,
wherein each of the battery cells includes:
a cell body; and
first and second electrode leads which protrude in opposite directions of the cell body,
wherein the first and second electrode leads are offset relative to each of the battery cells,
wherein m cell laminate blocks, each of which is obtained by lamination of a plurality of battery cells, are formed in the first direction,
wherein the m is an integer equal to or greater than 2,
wherein a second electrode lead of a p-th cell laminate block and a first electrode lead of a (p+1)-th cell laminate block are joined at a position facing each other in the battery cells,
wherein the p is an integer between 1 and (m−1),
wherein the reinforcing pole is disposed in a direction perpendicular to the first direction, and
wherein the reinforcing pole occupies a dead space adjacent to a portion where the second electrode lead of the p-th cell laminate block and the first electrode lead of the (p+1)-th cell laminate block are joined.
