結合器。[Claims for Utility Model Registration] In an optical coupler in which light emitted from a light emitting element enters an optical fiber via a lens, the light emitting element and the lens are arranged so that their optical axes are shifted from each other, and the light emitted from the optical fiber enters the optical fiber. An optical coupler characterized by being arranged so that the light enters at a constant angle of incidence.
