To provide a sliding surface formation method and a sliding surface shape in a sliding member reducing sliding resistance of sliding surfaces sliding each other and capable of preventing seizure and galling.
In the sliding surface formation method, the sliding surface 2 is formed on at least one sliding member 1 of the sliding members sliding each other. The sliding surface formation method is characterized in that it has a blade member pressing step for pressing a blade member 14 existing at a distal end of a working member 15 to one sliding member surface 2 moving in a direction approximately perpendicular to a sliding direction of one sliding member 1; an ultrasonic wave excitation step for applying ultrasonic vibration to the blade member 14; a blade member movement step for moving the blade member 14 pressed to one sliding member surface 2 along the sliding direction of one sliding member 1 at a predetermined speed; and a grinding step for uniformly grinding one sliding member surface 2 after the blade member movement step.
