Abstract: A heat releasing pipe includes a metal pipe and a surface coating layer. The metal pipe has an outer circumferential surface. The surface coating layer is provided on the outer circumferential surface of the metal pipe. The surface coating layer contains an inorganic glass base material and has concave portions and convex portions on an outer surface of the surface coating layer. The concave portions and the convex portions are constructed using electrocoating with an electrocoating resin. The concave portions have a virtually circular shape when seen in a direction perpendicular to the outer circumferential surface of the metal pipe and are lower than a first reference surface. The first reference surface has an average height of the outer surface of the surface coating layer. The convex portions are located on peripheral edge portions of the concave portions and surround the concave portions.
