結合器。 A collimating lens is provided at the tip portions facing each other, and the first and second optical fibers are opposed to each other at a predetermined distance on the same line, and the lens is orthogonal to the same line between the first and second optical fibers. In the optical splitting/coupling device, the third optical fiber has a collimating lens disposed at its tip at a predetermined distance from the same line, and a right-angle reflecting mirror for branching or coupling is located at a position perpendicular to the third optical fiber. 1. Cut diagonally the half of the opposite end surface of the collimating lens provided at the tip of each of the second optical fibers, which is located on the third optical fiber side, and apply a light shielding material to the cut surface. An optical branching coupler characterized in that:
