    A method of drawing an optical fiber preform for drawing the optical fiber preform to a smaller diameter preform rod (7) by heating/softening a preform ingot (1) in an electric furnace (3) and drawing it by a pair of pinch rollers (6) and (6). The method is characterized in that roller grooves (11) formed by a radius of curvature larger than the outer diameter of the preform rod (7) or V-shaped roller grooves (11) formed by a straight-line are formed in the peripheral surfaces of the pinch rollers (6) formed of a metal, and the preform rod (7) is held and drawn by the opposed roller grooves (11)and (11) of the pair of pinch rollers (6) and (6).
