ABSTRACT:
A photoelectric circuit board includes a substrate, an optical waveguide and a core exposure surface. The substrate has an inspection opening. The optical waveguide includes a core and a clad formed around the core. The optical waveguide is formed on one surface side of the substrate, is exposed to the inspection opening, and has a portion curved toward the inspection opening. The core exposure surface is formed in the curved portion of the optical waveguide so that the core is exposed out of the clad.
