PCT No. PCT/JP81/00185 Sec. 371 Date Apr. 27, 1982 Sec. 102(e) Date Apr. 27, 1982 PCT Filed Aug. 24, 1981 PCT Pub. No. WO82/00898 PCT Pub. Date Mar. 18, 1982.A method for producing an optical multiple fiber, which comprises bundling a multiplicity of silica glass light-conducting elements and drawing the bundle of the light-conducting elements in the state that a liquid intermediary material (comprising at least one member selected from the group consisting of glass forming oxides, glass modifying oxides and intermediate oxides) exists among the elements; thereby providing a multiple fiber excellent in image-transmitting capacity and image-resolving power, by fusing together a multiplicity of silica glass light-conducting elements with each other in drawing to prevent the occurrence of bubbles. |
