Summary:PROBLEM TO BE SOLVED: To provide a single crystal diamond cutting tool that can uniformly cut fine streaks on the surface of a workpiece without forming burrs. SOLUTION: In this single crystal diamond cutting tool, a single crystal diamond tip 3 is fitted to the tip of a shank and put in feed motion in a cutting direction and in a feed direction perpendicular to the cutting direction to a rotating workpiece to cut the workpiece. In this case, an auxiliary cutting edge 2 is formed at the front edge of a rake face 4 formed at the upper face of the tip, parallel with a feed direction along a line intersecting a front flank relief 5 formed at the front face of the tip, and a plurality of projections and recesses 8 in the cutting direction are formed at the auxiliary cutting edge 2 in the same pitch in the feed direction over the whole length.
