Abstract
An opto-electric hybrid board includes: an electric circuit board including an insulation layer and electrical interconnect lines formed on the front surface of the insulation layer; and an optical waveguide provided on the back surface side of the insulation layer of the electric circuit board, with a metal layer therebetween. At least one opening is formed by removing at least part of a region of the metal layer which is overlaid on the contour of an end portion of the optical waveguide. The optical waveguide is formed, with part of the optical waveguide extending into the opening. The opto-electric hybrid board is favorably usable over a prolonged period because the end portion of the optical waveguide provided on the back surface side of the electric circuit board does not peel off the metal layer.
