Abstract: The present invention relates to an optical coupling element to optically couple optical elements of different kinds to each other, which is provided with a plurality of cores. In the optical coupling element a first end and a second end opposed thereto are different in at least either of a core array and a core interval. The optical coupling element has a bent shape of at least a part of the optical coupling element itself including the cores, so that a light input/output direction at the first end is different from a light input/output direction at the second end.

Abstract: An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited.
