Abstract

PURPOSE:To obtain a long-sized light guide which has flexibility even after elongation with its manufacture process remarkably simplified, by forming a fusion- bonding proventive layer while the circumference of one end of an intermediate assembly is left, and by fusing and bonding in a body the part where the said layer is not formed by bundling those intermediate assemblies. CONSTITUTION:Materials are arrayed and thermally elongated to obtain an intermediate assembly and around this assembly, a fusion-bonding preventive film of high-melting point metal, such as molybdenum and indium, metal oxide, such as titanium oxide and magnesium oxide, etc., is bonded by vacuum deposition, chemical vapor deposition, etc. A plurality of the intermediate assemblies having the coating films bonded are arrayed and elongated finally. Consequently, the glass surface exposure parts of the intermediate assemblies are mutually bonded by fusion and the fusion bonding is prevented at the part of the preventive coating film. Therefore, a composite fiber bundle has flexibility on the whole and no disorder of respective fiber at both the ends.
