Abstract

PURPOSE:To prevent the disorder of the arrangement of optical fibers and to improve picture quality, by packing numbers of optical fibers in a quadrangular jacket pipe in an array state and removing the jacket pipe after forming them in one body by a collapse treatment, and thus repeating said stage. CONSTITUTION:Optical fiber wires 2 are packed regularly in the hole 3 of a quardrangular jacket pipe 1 in an array state. Then, a collapse treatment is carried out over evacuation, and the jacket pipe 1 is removed to obtain an image fiber base material 4. This is drawn by being heated to obtain an image fiber 5. This image fiber 5 is treated repeatedly as mentioned above in the order shown by an arrow in the figure, thereby obtaining a multiimage fiber base material 6. This is heated and drawn to obtain a prescribed multiimage fiber 7. With regard to the sectional structure of this fiber, there is no clearance as a dark part of light, so transmitted images of good quality are obtained.
