Abstract

PURPOSE:To improve heat resisance and fire resistance by interposing heat resistant powder consisting of a heat insulator between the nonheat resistant coating layer and metal coating layer of an optical transmission body. CONSTITUTION:This consists in interposing heat resistant powder of alundum, alumina or the like between the non-heat resistant coating layer 2 and metal coating layer 4 of an optical transmission body 1, and is produced by the method of supplying part of the powder 3 while a metallic tape 4 is in a flattened state or in the state of the figure (a) and again supplying the powder 3 when the tape 4 is worked to the state of the figure (b) then welding the butt parts of the tape like the figure (c) and finishing a cylindrical pipelike metallic coating layer 4. At this time, the void 15 existing there is reduced and erased when the layer 4 is pulled through dies and the layer 4 is therey reduced of diameter.
