Claim:
1. A battery pack comprising: a plurality of battery modules; at least one space that is formed between the battery modules that are adjacent to each other, and that serves as a flow path through which a heat carrier flows; and a plurality of protrusions that protrude toward an inside of the space, and that are arranged on surfaces of opposing surfaces that oppose each other and that define the space, wherein the plurality of protrusions that are arranged on one surface of the opposing surfaces and the plurality of protrusions that are arranged on the other surface of the opposing surfaces are arranged in positions that oppose each other across the space, wherein the protrusions have a longitudinal direction when viewed from a protruding direction of the protrusions, wherein the longitudinal direction of the protrusions is inclined with respect to a flow direction of the heat carrier in the space, that is a flow direction that excludes disturbed flow caused by the presence of the protrusions, and wherein the longitudinal direction of the plurality of protrusions that are arranged on one surface of the opposing surfaces is inclined with respect to the flow direction of the heat carrier in an inverse manner in relation to a direction in which the longitudinal direction of the plurality of protrusions that are arranged on the other surface of the opposing surfaces is inclined with respect to the flow direction of the heat carrier.
