Abstract
Opto-electric hybrid boards are disclosed including an electric circuit board; light-emitting and light-receiving elements which are mounted on a first surface of the electric circuit board; and an optical waveguide having a core for an optical path and formed in a stacked manner on a second surface of the electric circuit board. The core of the optical waveguide includes: end portions formed as light reflecting surfaces for reflecting light to allow the light to propagate between the core and the light-emitting and light-receiving elements; extensions extending from the end portion side of the core toward the light-emitting and light-receiving elements; and a main portion from which the extensions extend. The extensions of the core and the main portion of the core are different from each other in shape of cross-sections perpendicular to an axial direction thereof.
