Abstract

PURPOSE:To prevent the clogging of the glass tube inside by fine glass powder by suitably melting and vitrifying the fine glass powder being formed from the final end on the source outlet side of a moving heating source to the source outlet side at the time forming a glass film on the inside wall surface of the glass tube by a CVD method.
