Abstract
There is provided an opto-electric hybrid board including an optical waveguide including a linear core held between first and second cladding layers; electrical interconnect lines formed on a surface of the first cladding layer, with a light-permeable insulative layer therebetween; and a light-emitting element and a light-receiving element mounted on mounting pads of the electrical interconnect lines. Light reflecting surfaces for reflecting light are formed in end portions of the core. The light reflecting surfaces are concave surfaces curved in at least one of the width direction and the thickness direction of the core, and having a radius of curvature greater than 50 μm and less than 1500 μm as measured in the width direction of the core and a radius of curvature greater than 200 μm and less than 1500 μm as measured in the thickness direction of the core.
