In an optical contact unit and an optical connector using the optical contact unit, the optical contact and other components are integrated into a single unit which is collectively mounted and removed to and from the optical contact holding member so that the mounting and the removing operations is facilitated. The optical contact unit comprises an optical fiber with an end portion, a ferrule fitted onto the end portion of the optical fiber, a sleeve containing and supporting the ferrule so that the ferrule is movable in an axial direction thereof, a biasing member contained in the sleeve for biasing the ferrule to make the ferrule project from the sleeve in the axial direction, and a stopper for limiting the movement of the ferrule which is forced by the biasing member to move in the axial direction with respect to the sleeve. The optical connector comprises the optical contact unit of the above-described structure, an optical contact holding member having a receiving hole for receiving the optical contact unit, and a clip fixed in the receiving hole for locking the optical contact unit to the optical contact holding member.
