Abstract
To provide an electrical and optical hybrid board that has on one surface an optical waveguide and on the other surface an electrical interconnect pattern or the like, in which the core pattern and electrical interconnect pattern or the like are positioned in place with high accuracy, and a method of manufacturing the same. The method includes: preparing laminateof core layerand clad layeron an electrical wiring board; forming alignment markand electrical interconnect patternor electrical joint at the same time on a surface of the electrical wiring board opposite to a surface where laminateis formed, alignment markused for forming a core pattern of optical waveguide, the electrical joint used for connection with an external device; and forming a core pattern of optical waveguide on the basis of alignment markwithout using a photomask.
