PROBLEM TO BE SOLVED: To provide an optical fiber ferrule provided with an inclined surface and a notch by leading a laser beam to a rotating thin and long body, removing at least a part of a body outer surface and turning a remaining part into a prescribed shape. SOLUTION: An inner hole 110 is rotated around the axis in an axial direction. As the thin and long body 100 is rotated, the laser beam is led onto the outer surface and a part of the outer surface of the thin and long body 100 is removed. By leading the laser beam onto the outer surface of the thin and long body 100, the surface is shaped and the inclined surface and/or the notch is formed at a desired part along the length direction. In this case, the part of the thin and long body 100 is shaped by moving the laser beam 200 in the axial direction relatively to the thin and long body 100 or moving it oppositely. In such a manner, the thin and long body 100 is cut into a prescribed length after the inclined surface and/or the notch is formed and the optical fiber ferrule is formed.
