PROBLEM TO BE SOLVED: To provide an optical connector adapter excellent in dust resistance. SOLUTION: The optical connector adapter 3 of such a type that a shell-side hollow cylindrical portion 13 is integrally formed in a shell 12 constituting an outer shell, a sleeve holder 15 inserted in the shell 12 has a holder-side hollow cylindrical portion 16 and a sleeve 14 is held by the shell-side hollow cylindrical portion 13 and the holder-side hollow cylindrical portion 16 is provided. The shell 12 has an inward engaging projection 21 on a portion facing the holder-side hollow cylindrical portion 16 in the inner surface of the shell 12 while the sleeve holder 15 has a holder locking portion 22. By engaging the holder locking portion 22 with the engaging projection 21, the sleeve holder 15 is prevented from being removed from the shell 12. Further, the optical connector adapter 3 is attached to a housing so as to pass through a wall of the housing in such a direction that the shell-side hollow cylindrical portion 13 is located outside the housing and the holder-side hollow cylindrical portion 16 is located inside the housing.
