Abstract
The present invention relates to an optical fiber holding apparatus and the like, which has a structure for stably holding optical fibers with a satisfactory force without interfering with other components even when the apparatus is miniaturized. The optical fiber holding apparatus includes a stage for loading a front-end portion of the optical fiber and a lid section for sandwiching the optical fiber together with the stage. The lid section is rotatably connected with one end of an arm, and a fiber holding section is provided at the other end of the arm. The arm extends along the loading direction of the optical fiber and has such a length that the other end thereof is positioned outside of the lid section. Owing to this arrangement, the optical fiber to be held is pressed onto the stage at a further front-end side than the portion sandwiched by the stage and the lid section. As a result, a buffering space is ensured for avoiding interference with other components between the lid section and the optical fiber end face.
