Abstract
An electro-optical circuit board is provided, which includes an electrical wiring board and an optical wiring board. The optical wiring board includes a first metal substrate, an optical guiding layer formed on the first metal substrate, and a metal supporting structure formed around the optical guiding layer, wherein the optical guiding layer includes an optical waveguide and a clad wrapping the optical waveguide. When the electrical wiring board is joined with the optical wiring board through a laminating process, the metal supporting structure absorbs the pressure applied to the electro-optical circuit board.
