PROBLEM TO BE SOLVED: To provide a device and method for manufacturing optical coupling parts, which allow for having a desired amount of refractive index matching liquid adhered onto a front end face of an optical member and for increasing the film thickness of a refractive index matching material adhered to an optical coupling part.SOLUTION: An optical coupling part manufacturing device 10 is for manufacturing an optical coupling part comprising an optical fiber f with a refractive index matching material adhered to a front end face f1 thereof. A moving mechanism 1211 for moving the optical fiber f, an X-axis motor 1212, and a movement stage 122 adjust distance between the front end face f1 and a refractive index matching liquid 20 to a first distance L1, at which the refractive index matching liquid 20 held on a holding surface on a protruded portion 514 is attracted to the front end face f1 of the optical fiber f being electrically charged by an electrostatic generation unit 13 because of Coulomb force of the electrical charge, and then increase the distance. The electrostatic generation unit 13 provides electrical charge to the optical fiber f when the distance is the first distance L1, and continues to do so while the distance is being increased. |
