High-design sliding member

A method of manufacturing a sliding member comprising, on a surface of a metal substrate, a surface-treated layer comprising a zinc-plated layer, a chemical conversion-treated layer, and a topcoat layer sequentially stacked on the metal substrate,

• the chemical conversion-treated layer including chromium and oxygen,
• the topcoat layer is being a clear layer made of at least one material selected from the group consisting of a silica compound, acrylic resin, polyurethane resin, epoxy resin, phenol resin, and melamine resin,
• wherein a value of L* is 85 or greater, a value of |a*| is smaller than 6, a value of |b*| is smaller than 8, and a level of metallic gloss is 170 or greater on a surface of the sliding member according to a L*a*b* color system, and
• wherein the method comprises a step of forming the topcoat layer, on a surface of the chemical conversion-treated layer, and a step of forming the chemical conversion-treated layer before the step of forming the topcoat layer,
• the step of forming the topcoat layer is a process of forming the topcoat layer with an applied amount of 0.3 mg/m2 or greater and 8.0 mg/m2 or less, and
• the step of forming the chemical conversion-treated layer is a process of forming the chemical conversion-treated layer having a thickness in a range of 160 nm to 300 nm.
