子結合器。In an optical fiber/light receiving element coupler in which the end face of the optical fiber is sloped and the reflected light from the slope is incident on the light receiving element, the angle of inclination of the end face with respect to the axis of the optical fiber is such that the light is completely absorbed by the end face. An optical fiber/light receiving element coupler characterized in that the angle is set such that total reflection does not occur on the outer periphery of the optical fiber.
