PURPOSE:To exactly fix the tips of plural fibers in an arrangement position by applying a DC voltage between a substrate for fixing an optical fiber and the optical fiber, and joining the substrate and the optical fiber. CONSTITUTION:An optical fiber 1 is arranged in a groove 4 of a substrate, and thereafter, an electrode is brought into contact with the fiber, the whole is brought to a temperature rise to about 400 deg.C, and thereafter, the Si substrate side and the electrode 5 side are used as positive and negative electrodes, respectively, and when a voltage of about 60V is impressed, the Si substrate and the fiber are allowed to adhere closely by an electrostatic force, and thereafter, joined completely. The minimum thickness of a metal and glass required for this joining process is 2-4mum, and it is executed without passing through other impurities, therefore, the generation of an error of the center position of a core of the fiber, caused by a junction becomes extremely small. In such a way, the center position of the core of the fiber can be fixed to a desired position with high accuracy.
