Abstract
Among two main surfaces of a heat dissipation member, one main surface is curved to be convex in an outward direction and the other convex in an inward direction. When a straight line passing through both endpoints Pand Pof the curve is l, a point at which a distance to lon the curve is maximum is P, an intersection point between land a perpendicular drawn from Pto lis P, a middle point of a line segment PPis P, an intersection point between the curve and a straight line that passes through Pand is perpendicular to lis P, a length of the line segment PPis L, a length of a line segment PPis H, and a length of a line segment PPis h, (2 h/L)/(H/L) is 1.1 or more.
