摘要： PROBLEM TO BE SOLVED: To provide a sliding member improved in toughness of surface film excellent in wear resistance.SOLUTION: This sliding member is constituted so that it has a base material 1, an undercoat layer 2 formed on the base material 1, and a wear-resistant film 3 formed on the undercoat layer 2, where the thickness T1 of the wear-resistant film 3 and the thickness T2 of the undercoat layer 2 satisfy the relationship of formula 1 shown below, and the Young's modulus of the undercoat layer 2 satisfies formula 2 shown below. In this case, it is desirable that the wear-resistant film 3 has a Young's modulus of not less than 200 GPa and a Vickers hardness of not less than 800 HV(0.05). Moreover, it is desirable that the thickness T1 of the wear-resistant film 3 is 0.5 μm to 40 μm. Here, formula 1: T2/T1=2/8 to 8/2 and formula 2: ([the Young's modulus (GPa) of the wear-resistant film)] + [the Young's modulus (GPa) of the base material]÷2×0.92≤[the Young's modulus (GPa) of the undercoat layer]≤([the Young's modulus (GPa) of the wear-resistant film]+[the young's modulus (GPa) of the base material])÷2×1.08.
