One or a plurality of flat portions and one or a plurality of partial cylindrical portions connected to such flat portions are an exterior surface of a glass capillary tube for holding an optical fiber, with all partial cylindrical portions having the same single central axis and being defined by a common radius, and an insertion hole, into which an optical fiber is inserted and held, is formed at a position deviated from the central axis in a direction perpendicular to one of the flat portions, which serves as a benchmark.
