PROBLEM TO BE SOLVED: To contrive the speed-up of a process by utilizing both of electricity and light as signal transmission means between electronic circuit elements. SOLUTION: The semiconductor device 1 is provided with an electronic circuit element 11 formed on a semiconductor base board 10, a light emitting device 12 as well as a photo detector 13, which are formed on the semiconductor base board 10, and a waveguide passage 14 formed on the semiconductor base board 10. Light, emitted from the light emitting device 12 based on an electric signal produced in the electronic circuit element 11, is transmitted to the photo detector 13 through the waveguide passage 14 to convert the light, received by the photo detector 13, into an electric signal.
