PROBLEM TO BE SOLVED: To obtain an optical fiber connecting structure which does not increase optical splicing loss even when optical splicing of strong light intensity is made, and even when a frequency of attachment and detachment is high. SOLUTION: Collimator lenses 3 to which respective optical fibers 2 are coupled are fixedly housed in respective cylindrical holders 4. A pair of the cylindrical holders 4 with these built-in collimator lenses are opposed to each other in a sleeve 5 so that the collimator lenses 3 are spaced from each other. Since optical interconnection is performed by a non-contact method, the problem of damaging the splicing end faces does not occur in the case of attachment and detachment. Since the light path diameter is enlarged by the collimator lenses 3 in the optical interconnection part, the light intensity per unit area becomes weak, even if there are scratches and dust on the connecting end faces, the problem wherein the light burns the part of scratches and the dust and degrades the status of the end faces does not occur.
