A module for optical communication which is capable of securely preventing reflection even if there are variations in the urging force of a ferrule and also of protecting an antireflection member from damage. A holding stopper for holding an antireflection member and also for positioning a ferrule is installed coaxially in a housing. A ferrule holding member for holding the ferrule is coaxially mounted on the holding stopper. When the ferrule is urged by a spring or other urging member and inserted in the ferrule holding member, the distal end of the ferrule first comes in contact with the apex of the antireflection member, causing the antireflection member to deform according to the distal end surface of the ferrule, then the distal end of the ferrule comes in contact with the reference surface of the holding stopper so that it is positioned and fixed in the direction of an optical axis.
