Abstract
In a ferrule for a multi fiber optical connector of the multi stages where at least two layers of guide grooves and fiber holes are laminated, a distance of from a straight line that connect middle points between the center axes of the fiber holes that make up a fiber hole array at one end side in a laminating direction and the center axes of the fiber holes that make up a fiber hole array at another end side to an upper side of the entry is longer than a distance of from the straight line to a lower side of the entry. A ceiling of the entry is notched so that an inclination of the multi fiber tape is not regulated by the upper side of the entry when a leading end of each of the optical fibers is pressed against the corresponding guide groove while the multi fiber tape inserted from the entry is inclined toward the upper side of the entry. In a method of manufacturing a multi fiber optical connector, the multi fiber tape is inserted into the ferrule from the entry while being inclined obliquely downward.
