Abstract
A plate-shaped heat dissipation member includes a metal-silicon carbide composite containing aluminum or magnesium, in which at least one of two main surfaces of the heat dissipation member is curved to be convex in an outward direction of the heat dissipation member, and when a flatness of the one main surface defined by JIS B 0621 is represented by f1 and a flatness of the other main surface different from the one main surface defined by JIS B 0621 is represented by f2, f2 is less than f1 by 10 μm or more.
