が不要となる効果がある。As described above, according to the present invention, by enclosing a proper amount of the uncured ultraviolet curable adhesive inside the optical fiber connector ferrule, the assembly work of the optical fiber connector simply inserts the optical fiber into the ferrule. Since it only irradiates with ultraviolet rays, the number of assembly steps of the optical fiber connector ferrule can be reduced, and
There is an effect that it is not necessary to carry an adhesive, a stirrer, a measuring instrument, etc. to the assembly site.

When the position of the thin film is set appropriately, the optimum amount of adhesive required for bonding optical fibers can be enclosed in the ferrule,
There is an effect that it is possible to completely eliminate the adhesive coating operation that has been conventionally performed in the field, and the connection failure phenomenon of the optical fiber due to the unfilling of the adhesive, which has occurred in this coating operation. Further, in the present invention, since the uncured ultraviolet curable adhesive is sealed by the first thin film and the second thin film, the uncured state can be maintained for a long time. Moreover, since it is not necessary to remove these films in advance when the optical fiber is bonded and fixed, the work can be performed reliably and quickly.
