Abstract: A ferrule that holds an end part of an optical fiber includes a fiber hole into which the optical fiber is inserted and an upper wall part and a lower wall part that define a hollow adhesive filling part, where the lower wall part faces the upper wall part. The adhesive filling part is filled with an adhesive applied between the optical fiber inserted in the fiber hole and an inner wall surface of the adhesive filling part. The upper wall part has an upper opening through which the adhesive passes into the adhesive filling part, and the lower wall part has a lower opening that ventilates the adhesive filling part to outside of the ferrule.
