An optical connector includes a fiber-support block configured to couple cores of a plurality of optical fibers, and a lens-support block including a contact surface provided with a plurality of openings, the contact surface contacted to a contact surface of the fiber-support block, the cores of the optical fibers projecting from the contact surface of the fiber-support block insertable into the respective openings, the lens-support block having pairs of collimate lenses and convex lenses in the respective openings, each of the collimate lenses and a corresponding one of the convex lenses being spaced apart from each other in an optical-axis direction, the collimate lenses being movable in the optical-axis direction and being pressed by elastically deformable members, respectively, in the optical-axis direction and toward the contact surface of the fiber-support block.
