Abstract: An optical-electric printed wiring board includes an electric wiring substrate having electric interconnects, and an optical wiring layer stacked on the electric wiring substrate and having a surface on which an optical part is mounted. The optical wiring layer includes a core for propagating light, a clad for sandwiching the core, and a mirror for reflecting light propagating in the core toward an optical part mounted on the optical wiring layer, or reflecting light from an optical part into the core. The electric wiring substrate includes conductive setting portions each of which extends through the optical wiring layer in the direction of stacking and has an end face on which an optical part is set. These conductive setting portions obtain electrical conduction between the optical part and the electric interconnects.
