Abstract: PROBLEM TO BE SOLVED: To provide a multi-core optical connector which lessens the dependence on a superprecision molding technique and contributes to the stability of production technology. SOLUTION: This multi-core optical connector has an adaptor 10 which is provided with openings for inserting plugs 20 on both sides, is bored with a through-hole in the longitudinal direction at its center and in which coupling holes 11 are formed in the central parts of the front and rear surfaced on both sides, the plugs 20 which have coupling members 23 which are provided with the through-hole for inserting an optical fiber and are provided with engaging projections 24 to be inserted into the coupling holes 11 to fasten the plugs 20 to the adapter 10 in the upper and lower parts on their one-side ends, are provided with plug housings 21 for housing the plug bodies on the outside parts thereof and are attached and detached to and from both openings 12 of the adapter 10, ferrules 25 which are disposed on the one-side ends of the plugs 20, in which many fine holes 54 for inserting core 52 of optical fibers are bored in their centers in one row, and which execute the protection and alignment of the optical fibers and a sleeve 40 which is inserted into the central through-hole of the adapter 10 and supports both ferrules 25 so as to cover their outside parts to precisely align the optical fibers in the ferrules 25.
