摘要： There is provided a ferrule which has a fiber fixed hole into which an optical fiber can be inserted easily without being broken and which can provide a sufficient fiber bonding strength, and which can restrain variations in connection loss caused by the temperature variations.A ferrule 10 is provided with two alignment pin holes 10a into which alignment pins for positioning with respect to a mating ferrule are inserted, and a plurality of fiber fixed holes H formed at predetermined intervals between the alignment pin holes to insert optical fibers. Each of the fiber fixed holes H has at least a fiber guide hole 10d for guiding the optical fiber, a fiber hole 10c connected with the fiber guide hole to accommodate the tip end of the optical fiber, and a fiber insertion hole 10e connected with the fiber guide hole 10d to introduce the optical fiber into the ferrule. A connecting portion of the fiber guide hole 10d and the fiber insertion hole 10e is formed into a taper shape. And the fiber insertion hole 10e is formed so as to introduce the sheathed portion of individual optical fiber.
