Abstract
An optical part, which is used to be placed at an end face of an optical fiber, is constituted by a single light-transmitting material transparent to light transmitted through the optical fiber, and comprises an optical fiber contacting facedisposed in contact with the end face of the optical fiber, and an light emitting facetilted with respect to a cross section perpendicular to the axis of the optical fiber. Since the light emitting faceis formed with an inclination, such an optical partrestrains reflected light occurring at the optical fiber end face from going back to the optical fiber. Also, since the optical partis constituted by a single light-transmitting material, its configuration is simple, and the length can be shortened in the optical axis direction.
