Abstract:
1. A material for an optical circuit-electrical circuit mixedly mounting substrate comprising: a light permeable resin layer, a metal layer which is to be formed into an electrical circuit, and an optical circuit forming layer that is made of a light permeable resin of which solubility to a solvent changes when irradiated with an activating energy beam and is disposed adjacent to the light permeable resin layer, wherein the light permeable resin layer is disposed between the metal layer and the optical circuit forming layer, wherein when the activating energy beam is applied to the material for the optical circuit-electrical circuit mixedly mounting substrate so that a portion of the optical circuit forming layer is irradiated with the activating energy beam, a refractive index of the optical circuit forming layer is higher than that of the light permeable resin layer; said portion of the optical circuit forming layer irradiated with the activating energy beam changes from a state of being removable by dissolving into a solvent to a state of being insoluble; and the rest of the optical circuit forming layer that is not irradiated with the activating energy beam remains in the state of being removable by dissolving into the solvent.
