The raw material discharged from the raw material blowing nozzle 3 becomes glass fine particles by a hydrolysis reaction or an oxidation reaction due to the combustion of the supporting gas emitted from the supporting gas blowing nozzle 4 and the combustible gas discharged from the combustible gas blowing pipe 2. A porous optical fiber preform is obtained by spraying and depositing the glass particles on the outer periphery of a target such as a seed rod that reciprocates while rotating. A method of manufacturing such an optical fiber preform is called an external attachment method. In this external attachment method, the outer diameter of the optical fiber preform obtained is gradually increased as the deposition of glass particles on the target progresses.
