Title: Method for Producing Optical Multiple Fiber Abstract A method for producing a 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 inter- mediary material exists among the light-conducting elements, said intermediary material being at least one member selected from the group consisting of glass network forming oxides, glass modifying oxides and intermediate oxides. When a multiple fiber is produced by this method, the respective light-conducting elements are fused together with each other in good state and occurrence of bubbles is prevented, thus providing a multiple fiber excellent in image-transmitting capacity and image-resolving power.
