Abstract
An opto-electric hybrid board includes an electric circuit board, an optical waveguide, and a metal layer. The electric circuit board includes an insulative layer having front and back surfaces, and electrical interconnect lines formed on the front surface of the insulative layer. The optical waveguide includes a first cladding layer and cores, and the optical waveguide is formed on the back surface of the insulative layer of the electric circuit board. The metal layer is formed between the first cladding layer of the optical waveguide and the back surface of the insulative layer of the electric circuit board. Part of the opto-electric hybrid board is formed as a to-be-bent portion. The metal layer is partially removed in a portion corresponding to the to-be-bent portion. A first cladding layer of the optical waveguide fills a site where the metal layer is removed.
