A method for forming a circuit board structure of composite material is disclosed. First, a composite material structure including a substrate and a composite material dielectric layer is provided. The composite material dielectric layer includes a catalyst dielectric layer contacting the substrate and at least one sacrificial layer contacting the catalyst dielectric layer. The sacrificial layer is insoluble in water. Later, the composite material dielectric layer is patterned and simultaneously catalyst particles are activated. Then, a conductive layer is formed on the activated catalyst particles. Afterwards, at least one sacrificial layer is removed.
