PURPOSE:To provide a support member for drawing of a base material for an optical fiber causing no deformation or occurrence of eccentricity at the time of operation. CONSTITUTION:This support member for drawing of a base material for an optical fiber supports a cylindrical glass body as a base material for an optical fiber at one end in a process for producing an optical fiber by heating and drawing and is made of ceramics contg. <=0.5wt.% volatile metallic impurities and having >=1,600 deg.C softening temp. or decomposition temp. |
