Abstract:
Provided is a method of manufacturing an optical fiber base material by an inside mounting method, including: a step of rotating and heating a glass tube fixed at two positions and supplying a gas into a through-hole of the glass tube, wherein in the step, the glass tube is warped so that an axis between respective fixed portions of the glass tube has a shape in which a catenary curve is reversed in the vertical direction.
