1. An optical fiber cable connecting structure, comprising:
a substrate having a through hole; an optical element mounted on a first surface of the substrate and having a light receiving unit for inputting an optical signal or a light emitting unit for outputting the optical signal, the light receiving unit or the light emitting unit being provided to face the substrate; an optical fiber cable mounted on a second surface of the substrate opposite to the first surface on which the optical element is mounted, an end face of the optical fiber cable on a substrate side being covered with a jacket; a guide positioning part that has an insertion hole into which the optical fiber cable is configured to be inserted to hold the optical fiber cable, the guide positioning part being configured to position the optical fiber cable with respect to an emitting direction of light that is input and output via the through hole from the optical element; and an abutting part that has an opening whose cross-sectional area on an optical fiber cable side is larger than that of the end face of the optical fiber cable and is reduced either stepwise or continuously towards the optical element, the abutting part being configured to position the optical element and the optical fiber cable so as to be separated by a specified distance by fixing an outer periphery of the end face of the optical fiber cable by the opening. |
