The suction hole is in communication with the suction face. In the suction face, an area ratio of an area occupied by the second grains to a measurement face obtained by polishing the suction face is greater than or equal to 17% but less than or equal to 34%. A number of the second grains in an area of 90 ?m2 in the measurement face is greater than or equal to 150 but less than or equal to 250.
