A composite optical fiber for use with a sensor includes an imaging optical fiber which receives information-carrying light that is reflected from a target, and a transparent material that includes the imaging optical fiber in its interior and which transmits an illuminating light from a light source to the target. The light-receiving optical fiber is an integral part of the transparent material, and it has an increased cross-sectional area for transmitting the illuminating light with respect to its overall outside diameter. The optical fiber can be produced by the extrusion technique without arranging a multiplicity of light-transmitting fibers and encasing them within a heat-shrinkable tube.
