PROBLEM TO BE SOLVED: To provide an optical ferrule that has high reliability for a long period of time by minimizing the effect of an adhesive. SOLUTION: The optical ferrule is for housing a coated optical fiber 10 whose coating is removed at the end, with the optical fiber 11 exposed by a prescribed length. The ferrule is composed of a flange section 15 and a zirconia section 16 which are connected to each other and integrated. In the flange section 15, the coating 12 of the coated optical fiber is fixed with an adhesive 25 inside a coating housing hole 18 while, in the zirconia section 16, the optical fiber 11 is fixed with the adhesive 25 inside the optical fiber housing hole 17. The part being a gap between the coating housing hole 18 and the coating 12 of the coated optical fiber 10 and filled with the adhesive 25, is set to have a thickness of 0.01-0.2 mm.
