PURPOSE:To improve the array quality of plural optical glass fiber consisting of a core and a clad and the uniformity of the distance between adjacent fibers by arranging plural glass fibers on a glass body in parallel, and welding part of the clads of the glass fibers to the glass body. CONSTITUTION:All optical fibers 1 are welded to the common glass body 8 at part 7 of their circumferences. Namely, the optical fibers 1 and glass body 8 are united lengthwise in terms of structure. This structure allows the individual optical fibers to be discriminated. For the purpose, plural preforms 12 are arrayed closely and supplied to heating furnaces 15 which function individually and then heated in the heating furnace 15. The glass body 13, on the other hand, is supplied to the heating furnaces 14 and also heated in the heating furnace 14. Those are heated individually and the both are assembled in the state where the surface of the glass body 13 is parallel to the array surface of the plural optical fibers when they are fused, thereby welding the respective optical fibers onto the glass body. |
