A ferrule (10), comprising a ceramic tubular body (20) for ferrule having an optical fiber insert hole (22) for inserting an optical fiber (1) and an optical fiber core insert hole (23) for holdingly inserting an optical fiber core (2) obtained by applying coating on the optical fiber (1) provided in communication with the optical fiber insert hole (22), and a flange member (30) fixed only to the outer peripheral surface of the tubular body (20) for ferrule, whereby, since the ferrule is formed only of the tubular body (20) for ferrule and the flange member (30) fixed only to the outer peripheral surface of the tubular body (20) for ferrule, the weight of the flange member (30) can be reduced, and the production cost of the ferrule can be lowered.
