    Abstract: An opto-electric hybrid board that sequentially includes an optical waveguide and an electric circuit board toward one side in a thickness direction. The electric circuit board includes a metal supporting layer, an insulating base layer disposed on a one-side surface in the thickness direction of the metal supporting layer, a plurality of conductive layers sequentially disposed at one side in the thickness direction, and an intermediate insulating layer disposed between the conductive layers. At least one layer selected from the group consisting of the metal supporting layer and the conductive layers is electrically insulated from the other layers.
