    • PROBLEM TO BE SOLVED: To provide an optoelectric integrated circuit device which can prevent the clock skew, even the level of integration is increased, and is capable of processing signals at high speeds. SOLUTION: An electronic element layer 4, provided with electronic elements D, an electronic wiring layer 2 provided with electronic wirings W, a light guide surface 3, a plurality of light-emitting elements L1 and so on and a plurality of photodetecting elements P1 and so on are disposed on the same substrate 1, the electronic elements D and the electronic wirings W constitute circuit blocks B1 and so on the light-emitting elements are connected to an output part, and the photodetecting elements are connected to an input part. The light emitting elements and the photodetecting elements are coupled on the same light guide surface, the photodetecting elements couple signal light pulses intensity-modulated by signals and clock light pulses intensity-modulated by a clock frequency with the same light guide surface, and the photodetecting elements receive the clock light pulse to control the clock frequency and phase of the circuit blocks.
