Abstract

An opto-electric hybrid board which is excellent in the mountability of an optical element and in flexibility is provided. The opto-electric hybrid board includes an electric circuit board (E), an optical waveguide (W), and metal layers (M). The electric circuit board (E) includes an insulative layer (1) having front and back surfaces, and optical element mounting pads (3) formed on the front surface of the insulative layer (1). The optical waveguide (W) includes a first cladding layer (6), and is formed on the back surface of the insulative layer (1) of the electric circuit board (E) in such a manner that the first cladding layer (6) is in contact with the back surface of the insulative layer (1). The metal layers (M) are provided between the insulative layer (1) and the first cladding layer (6) and disposed in corresponding relation to the optical element mounting pads (3). The metal layers (M) have a yield stress or 0.2% proof stress of not less than 170 MPa and a thickness in the range of 10 to 25 µm.
