    • PROBLEM TO BE SOLVED: To provide a forming method of a nitrided sliding face for applying nitriding to the sliding face and forming a recessed part (a minute recessed part).
      SOLUTION: This forming method of the nitrided sliding face comprises a process for obtaining roughly machined sliding faces 46, 47, 48 by machining sections 42, 43, 44 corresponding to the nitrided sliding faces 18, 19, 21 roughly in a raw material 41, a process for forming a plurality of recessed parts 52 by spraying a plurality of beads 51 on the roughly machined sliding faces 46, 47, 48, a process for applying nitriding treatment to the roughly machined sliding faces 46, 47, 48 with the plurality of recessed parts 52 formed, and a process for obtaining nitrided sliding faces 18, 19, 21 by finish-machining the roughly machined sliding faces 46, 47, 48 so that a ratio Rs of opening area of the recessed part becomes 5 to 10 % per unit area and a ratio Rv of volume of the recessed part becomes 2 × 10
