The utility model discloses a composite insulator for a high voltage fuse, and relates to the composite insulator which comprises a mandrel, an umbrella skirt, and a middle fitting which is connected between two ends of the mandrel. The two ends of the mandrel are connected with an end part fitting; the umbrella skirt is arranged at an outer side face of the mandrel by injection molding; the surface of the umbrella skirt is provided with a die assembly seam; and when the insulator works, the die assembly seam is not in line with one of two intersecting lines which is closer to the ground, wherein the two intersecting lines are formed by intersection of a surface and the surface of the umbrella skirt, and the surface goes through the mandrel axis and is perpendicular to a horizontal plane. According to the composite insulator for the high voltage fuse of the utility model, the die assembly seam on the umbrella skirt surface is not located at a place closest to the ground of the umbrella skirt; in the composite
