摘要： PROBLEM TO BE SOLVED: To easily produce a base material for an optical fiber at a low cost by integrating a glass pipe with a glass rod and drawing them at the same time. SOLUTION: A glass rod 2 as a core or a core and clad is inserted into a glass pipe 1 as a clad to integrate and draw them at the same time while heating them by a heater 3 and reducing the pressure inside the glass pipe. An obtained glass rod obtained by dehydrating and sintering an accumulated body of fine particles of glass is used as it is by skipping a drawing step to adjust the outside diameter of the glass rod to meet with the inside diameter of the glass pipe. The glass pipe and the glass rod are integrated so that a desired core/clad ratio at the position to integrated them is obtained by relatively adjusting the introducing velocity VR of the glass rod to the heater 3 to the introducing velocity VP of the glass pipe.
