S-2-21013M/HK/79 ABSTRACT OF THE DISCLOSURE A method of manufacturing an optical transmission fibers comprising forming glass particles by subjecting glass raw material gas to flame hydrolysis, forming a cylindrical glass particle body by supplying the glass particles thus formed onto a starting member so that the glass particles are laminated thereon and successively grown and sintering the cylindrical glass particle body to provide a transparent glass cylinder. The transparent glass cylinder is inserted into a quartz glass pipe to provide the assembly of the transparent glass cylinder and the quartz glass pipe. The assembly is heated to melt the glass cylinder and the quartz glass pipe together and the assembly is drawn into a thin fiber.
