PROBLEM TO BE SOLVED: To provide an optical connector ferrule, an optical connector and a coated optical fiber, with the optical connector which are capable of preventing the coating of the coated optical fiber from falling off. SOLUTION: In the optical connector ferrule 10, an adhesive 31 is allowed to flow into the inserting hole 12b of a coated optical fiber (fiber) in a fiber storing member 12 and, with the fiber 20 inserted, a part of the adhesive 31 is solidified in a state left in a recess 14 which is formed on the inner wall of the fiber inserting hole 12b. Consequently, in a part of the outer circumference of a polyamide layer 22B of the fiber 20, there is formed a projection 16 of the solidified adhesive in a shape coincident to the recess 14. As a result, in the occurrence of separation in the boundary between the adhesive 31 and the fiber storing member 12, an anchoring effect caused between the projection 16 and the recess 14 can prevent the coating 22 of the fiber 20 from falling off from the optical connector ferrule 10.
