An optical connector according to the present invention has a ferrule body provided with a fiber positioning hole, a pair of guide holes into which guide pins are inserted, and a connecting end face in which ends of the fiber positioning hole and guide holes open. A chamfer portion equivalent to a part of a surface of a body of revolution is formed at each guide hole on the connecting end face side. Further, the connecting end face is formed at an angle relative to a plane normal to the center axes of the pair of guide holes. In this structure, the slope of the connecting end face can suppress degradation of connection loss, and the provision of the chamfer portions can facilitate insertion of the guide pins, prevent damage of the connecting end face due to the guide pins, and also suppress degradation of connection loss due to the damage.
