ABSTRACT:
A built-in optical fiber of a ferrule has one end of the built-in optical fiber matched with a splicing end surface, and the other end of the built-in optical fiber protruded from an end portion opposite to the splicing end surface and one end of a splicing optical fiber to be spliced are placed so as to be fusion-sliced with one another. After that, the ferrule is held by inserting a cylindrical portion of the ferrule into a holding unit of a ferrule holder from the splicing end surface. The ferrule is transferred while holding a stem extended on an opposite side of the holding unit of the ferrule holder and the splicing optical fiber.
