損が起き易くなるという問題があった。(Problems to be Solved by the Invention) The above-described conventional manufacturing method has a drawback in that alignment is not easy because the optical fibers are disposed on a relatively highly viscous adhesive. In addition, it takes time to apply the adhesive evenly with VC, and air is trapped when the optical fiber is sandwiched and bonded. There is a drawback that an inner 8Vc bubble is generated. These bubbles not only reduce the adhesive strength of the optical fiber and the insulator, but also create areas where stress is concentrated in the optical fiber after it is fixed, causing the problem that the optical fiber is more likely to break in these areas. there were.

泡も除去することができる。(Means for Solving the Problem) The method for manufacturing an optical fiber array according to the present invention involves aligning and fixing optical fibers in advance using an optical fiber support and an optical fiber cord support. The optical fibers are aligned and fixed temporarily without contacting the optical fiber T-adhesive, and the fixed optical fibers are placed in a container shaped like the outer shape of the optical fiber array, and liquid resin is poured into the container and vacuum is applied. It is designed to be cured after defoaming, so that an effective alignment state can be obtained, there is no need to apply adhesive, and internal air bubbles can also be removed.
（実施例） 次に、本発明を図面を参照して実施例につき説明する。(Example) Next, the present invention will be explained by way of example with reference to the drawings.
