Beschreibung
Zusammenfassung:	A substantially rectangular flat heat dissipation member includes: a composite portion where silicon carbide having voids is impregnated with metal; and a metal portion that is different from the composite portion. Here, a proportion of a volume of the metal portion to a total volume of the heat dissipation member is 2.9% or higher and 12% or lower. In addition, when a length of a diagonal line of the rectangular flat heat dissipation member is represented by L, in a top view where one main surface of the heat dissipation member is a top surface, 40% or higher of a total volume of the metal portion is present in a region D within a distance of L/6 from an apex of any one of four corners of the heat dissipation member. Further, a hole penetrates the metal portion in the region D.
