Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a monofilament capable of being used as a bristle for a tooth brush. SOLUTION: Each monofilament has a diameter within a range of 0.0025-0.012 inch, and a six-follicles or eight-follicles shape. The monofilament is produced by a step for extruding two or more thermoplastic polymer flows, a step for rotating two or more blades at >1,000 rpm, and a step for forming split tips by arranging the two or more blades so as to contact with the terminal parts of the two or more thermoplastic polymer flows.
