- the above embodiments of the present invention mainly describe the case where the arrangement of the plurality of optical fibers is configured in two stages, but the present invention is configured in the case where the present invention is configured in one stage or three stages or more. However, the same can be applied. Even in this case, since the filler having a large filler particle size is arranged around the fine hole group, the structure around the fine hole group has an increased hardness. Since the small diameter is arranged, the fine holes are formed with high accuracy.
