A ferrule with fiber holes includes: a resin-molded portion molded by a resin; and a reinforcement member embedded in the resin-molded portion and that has a smaller linear expansion coefficient than the resin-molded portion. The reinforcement member includes fiber insertion portions that are parallel to the fiber holes. The fiber holes are formed by the resin that entered the fiber insertion portions.
