An optical connector comprises a sleeve having a flange provided on one end surface of a hollow cylinder, a collimator lens which is press-fitted or fitted into and then bonded to the sleeve, and an optical fiber fusion-welded to the end surface of the collimator lens fixed to the sleeve on the side opposite to the flange side. The optical connector is characterized in that the end surface of the flange is formed in a flat surface vertical to the optical axis, and the collimator lens has the focal point on the end surface thereof on the side opposite to the flange side.
