Abstract: A method for manufacturing a glass preform for use in optical fiber comprises flame hydrolyzing a glass raw material in an oxyhydrogen flame to form fine glass particles of quartz, depositing the particles on a seed member to produce a solid or hollow cylindrical shoot preform which contains GeO2, and heating and sintering the preform, wherein the preform contains 10-80% by weight of GeO2, the sintering atmosphere consists of an inert gas, at least a part of the atmosphere is kept at 1,600-2,000≦̸C, and the preform is introduced at 3-20 mm/min.
