Provided are an optical connector and an optical tomographic imaging apparatus, by which no noise occurs and a high quality image without a distortion can be obtained. In the optical connector, optical fibers are inserted into a lumen of a tube from opposite ends thereof; one of the optical fibers is fixed to the tube and the other optical fiber is held so as to be rotatable relative to the tube; an end of one of the optical fibers is separated from an end of the other optical fiber to form a gap therebetween in the lumen; a connecting section which connects the exterior space of the tube and the gap is formed; and a liquid or fluid made of a material which can transmit light is held in the exterior space, the gap, and the connecting section. Consequently, a significant pressure variation in matching liquid does not occur if the distance between the facing optical fibers changes
