    • PROBLEM TO BE SOLVED: To provide an optical connector capable of turning the optical axis of an optical fiber to an optical element with high accuracy.
      SOLUTION: This optical connector 1 is constituted so as to perform optical splicing between an optical fiber 3 and an optical element 5 by being attached to the tip part of the optical fiber 3 and by being installed while being confronted with the optical element 5 of an optical tranceiver 4 on a circuit board 6. In the optical connector 1, a connector main body 2 has a hollow part 8 for holding the optical fiber, an optical fiber hole 9 and a recessed part 11 for changing the optical axis of the optical fiber 3 and in the recessed part 11 for changing the optical axis, a reflecting surface 10 for changing the optical axis which turns the optical axis of the optical fiber fiber 3 to the optical element 5 is formed. Thereby, since the mutual positional relationship between the optical axis of the optical fiber 3 and the reflecting surface 10 for changing the optical axis is fixed with high accuracy, the changing of the optical axis for turning the direction of the optical axis of the fiber 3 to the side of the optical element 5 can be performed with high accuracy and loss of the optical splicing between the optical fiber 3 and the optical element 5 can be reduced.
