PROBLEM TO BE SOLVED: To provide a heat dissipation component in which thermal deformation is prevented after ensuring heat dissipation performance, and also to provide a heat dissipation structure. SOLUTION: The heat dissipation component positioned on a flow passage of a heat medium for heat exchange with the heat medium is provided with a plate-like base portion 1 and wall-like fins 3 extending to the base portion 1, wherein the extension shape of each of the wall-like fins has a length component in a direction (x-direction) perpendicular to the flow passage direction, and a length component along the flow passage is <1/2 of the length of the base portion.
