Opto-electric hybrid board and method of manufacturing same

摘要

An opto-electric hybrid board which is capable of suppressing the increase in light propagation losses and which is excellent in flexibility, and a method of manufacturing the same are provided. The opto-electric hybrid board includes an electric circuit board (E), an optical waveguide (W), and a metal layer (M). The electric circuit board (E) includes an insulative layer (1) having front and back surfaces, and electrical interconnect lines (2) formed on the front surface of the insulative layer (1). The optical waveguide (W) is formed on the back surface of the insulative layer (1) of the electric circuit board (E). The metal layer (M) is formed between the optical waveguide (W) and the back surface of the insulative layer (1) of the electric circuit board (E). The metal layer (M) is patterned to have a plurality of strips (Ma). Cores (7) of the optical waveguide (W) are disposed in a position corresponding to a site (R 1 ) where the metal layer (M) is removed by the patterning.
