摘要： PROBLEM TO BE SOLVED: To provide a line drawing method of an optical fiber which can appropriately control line speed. SOLUTION: The line drawing method of an optical fiber in which one end of an optical fiber preform 1 consisting of glass is heated and melted, and a glass optical fiber 3 is line drawn from the end is characterized in that a total volume of the glass optical fiber which has been line drawn is measured, and controlling which alters a line speed of the glass optical fiber 3 is performed based on the total volume which has been measured. The line drawing method of an optical fiber desirably includes: a first line drawing process which line draws the glass optical fiber 3 at a first line speed; and a second drawing process which accelerates a line speed of the glass optical fiber 3 from the first line speed to a second line speed when the total volume which has been measured reaches a prescribed value.
