摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical fiber preform in which a taper part in the finishing time of drawing is used as an insert starting end by preventing an increase in outside diameter of the drawn rode just before the finishing of drawing in the formation of a large and long sized rod by drawing a primary preform in a rod-in-tube method. SOLUTION: In the formation of long sized rod 2 by heating and drawing a large sized quartz rod material 1, the drawing temperature is decreased and the drawing speed is increased after the quartz rod material 1 is drawn by a length necessary for inserting into a tube to fuse and integrate. As a result, it is prevented from forming an outside diameter increased part at the lower end part of the rod 2. Thus, when the rod 2 is inserted into the tube, it is not caused that the lower end part of the rod 2 is caught by an inlet of the tube to disturb the insertion of rod 2 or brought into contact with the inside surface of the tube to give defects.
