Abstract

PURPOSE:To improve the occupation rate of a core in the end surface of a light guide, to prevent thermal deterioration, and to improve large-light-quantity transmission, by fixing the end part of a bundle of many optical fiber by a heat- resisting fixation, part. CONSTITUTION:At the bundle end part 6 of optical fibers 1 and 1,... end parts 5 and 5,... of the optical fibers are fixed in one body, and in this case, a heat- resisting fixation part 7 is formed neither by winding the external circumference of the bundle part 6 with a metallic wire or by fitting a glass tube around the external circumference of the bundle part 6 while the tube is not melt-stuck to the respective end parts 5 and 5,.... Consequently, cladding materials 3 and 3,... come into facial contact and the end parts 5 and 5,... are bundled at the bundle end part 6, so unnecessary space is formed to increase the occupation rate of each core 2 and 2,... in the end surface. In addition, none of film layers 4 and 4,... which are thermally weak extend to the bundle end part 6, so thermal deterioration is never caused, so that large-light-quantity transmission is carried out without any trouble.
