Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sliding member of high adhesivity between a base material and a film and of excellent wear resistance, and a method for manufacturing the same. SOLUTION: The sliding member is formed by covering a film consisting of iron nitride and iron carbo-nitride on a base material consisting of iron-based alloy. The base material is formed of steel containing C, Si, Mn and Cr of predetermined quantities, and the balance Fe, wherein [C] of a surface of the base material is 0.6-1.4%, [N] is 0.2-2.0%, and the H value expressed by H=1.1 x [C] + 1.5 x [N] + 2.8 x [Mn] + 1.0 x [Si] + 0.6 x [Cr] + 2.6 is ≥ 6.5%. The film containing iron nitride and iron carbo-nitride is deposited on the base material consisting of iron-based alloy at the treatment temperature of 150-250°C, and other films are successively covered thereon to manufacture the slide member.
