An optical connector ferrule (11) has an optical fiber containing hole (16) reaching from the rear end surface (11b) near the end surface (17) and a fine pore (14) extending from the optical fiber accommodating hole (16) to the end surface (17) to be connected. A bare fiber (15b) of a polarization-maintaining optical fiber (15) is inserted into the fine pore (14). Since the length of the fine pore (14) is short, the influence of the uniformness of the adhesive in the fine pore (14) is smaller, and therefore the stress distribution is maintained, resulting in stabilizing the polarization characteristics. A flange unit (18) is attached to the ferrule (11) after an optical fiber (15) is inserted to the ferrule (11) and fixed. Therefore the optical fiber (15b) is easily adjusted with respect to the housing in the circumferential direction around the axis, and optical fibers are connected by but joining with high accuracy. <IMAGE> |
