PROBLEM TO BE SOLVED: To provide a flange having a satisfactory squareness of the flange face with respect to a cylindrical part, and an airtight contact face to a counter member, in sintered parts having the cylindrical part and the flange. SOLUTION: The sintered parts 40 comprise the cylindrical part 41 having an axial length L1 of at least 20 mm, a wall thickness t1 of 2 mm or less, and a major diameter d1 of 70-150 mm, and the flange 42 having an axial wall thickness D1 of at least 3 mm, and a major diameter at least 5 mm larger than the major diameter d1 of the cylindrical part 41, wherein the squareness of an internal circumferential surface 41a of the tubular part 41 against the end face 42a of the flange 42 is made to be 0.03 mm or less.
