いる。FIG. 1 shows an example of a conventional optical fiber fixing device. FIG. 1 shows a section taken along a plane perpendicular to the axis of the optical fiber. In FIG. 1, 1 to 7 are optical fibers, and these optical fibers 1 to 7 are connected to the optical fiber 1 by a thin metal wire 8.
They are closely arranged on a concentric circle with their respective axes positioned at the vertices of a regular hexagon, and further fixed with resin 9.

本発明は上記従来の欠点で除去するものであり、以下に
本発明の一実施例について第２図とともに説明する。However, in the above conventional example, since the optical fibers 1 to 7 with a diameter of several hundred microns are tied together with the metal wire 8 at one location,
The optical fibers 1 to 7 are likely to break, and the axes of the fibers 2 to 7 are likely to deviate from the apex positions of the regular hexagon, making it impossible for the light from the optical fiber 1 to enter a predetermined optical fiber 2 to 7. There were drawbacks. In addition, since the surrounding resin 9 is used to fix the optical fibers 1 to 1, due to the difference in thermal expansion coefficient,
The present invention is intended to eliminate the above-mentioned conventional drawbacks, and an embodiment of the present invention will be described below with reference to FIG. 2.

用の樹脂である。In FIG. 2, 10 to 19 are optical fibers having approximately the same diameter, and 17 to 19 are dummies. The optical fiber 20 has a groove 20a with an opening angle of 6d), and the thermal expansion coefficient processed by laminating or etching is the same as that of the optical fiber 10.
- 19 is a fixing member made of hard glass or the like, 21 is a pressing member made of the same material as the fixing member 20, and 22 is an adhesive resin.

べ小さくなる利点を有する。In this embodiment, ten optical fibers are arranged in a V-shaped groove 2°a, and six optical fibers 11 to 16 are automatically formed around one optical fiber 10 by simply pressing it with a holding member 21. Since the respective axes are arranged at the vertices of a regular hexagon, there is an advantage that no skill is required for the operation. ! , fC,, unlike the conventional example, the groove 20a of the fixing member 20 and the pressing member 2
Since force is applied to the optical fibers 11 to 19 from the plane 1, it has the advantage of being less likely to break. Also, the fixing member 20. Pressing member 21
Since the coefficient of thermal expansion of the optical fibers 10 to 19 is close to that of the optical fibers 10 to 19, there is an advantage that fluctuations in the axial direction of the optical fibers are smaller than in the conventional example.
