PROBLEM TO BE SOLVED: To improve appearance of an exhaust system part by making tone of color different from each other between one part and the other part of a surface of the exhaust system part, when glass fine particles are dispersedly fixed to a surface of a metallic member provided on the exhaust system part. SOLUTION: On a surface 16a of a metallic member 16 to be heated from an internal side with the heat of an exhaust 13, glass fine particles are dispersedly fixed. Values for the ratio of area of a surface exposed to the outside of glass fine particles per unit area of the surface 16a of the metallic member 16 are made different from each other in one part 16a (A) of the surface 16a of the metallic member 16 and the other part 16a (B) around this one part 16a (A).
