Abstract
A photoelectric mixed substrate includes a wiring substrate including a first ground wire, a signal wire arranged above the first ground wire and electrically connected to the photoelectric component and the electronic component, and a waveguide unit stacked on the wiring substrate to cover the signal wire. The waveguide unit includes a first clad layer formed on the wiring substrate, a second ground wire formed above the first clad layer, a core formed on the first clad layer and optically coupled to the photoelectric component, and a second clad layer formed on the first clad layer to cover the core.
