| abstract | (57) [Problem] To provide a compact, lightweight, low inertia, less susceptible to vibration, eliminate the steps of assembling and adjusting individual parts, enable mass production, and realize cost reduction. A light emitting diode (12) is provided on a semiconductor substrate (11). , A photodiode 13, and film-shaped optical waveguides 14 and 15 including three layers of a lower clad layer 16, a core layer 17, and an upper clad layer 18 are formed. Then, the convex portions 14a and 1a provided on the end faces of the optical waveguides 14 and 15 are formed. 5a and the objective lenses 19 and 20 reflect the light beam 27 emitted from the light emitting diode 12 to an object 30 outside the device, and make the reflected light incident on the optical waveguide 15 as a light beam 31; To receive light. |
