摘要

PROBLEM TO BE SOLVED: To provide a copper foil with a carrier which adheres suitably to a resin and is excellent in transparency of a resin after removing the copper foil by etching and to provide a laminated board using the same.SOLUTION: There is provided a copper foil with a carrier in which roughened particles are formed on an ultrathin copper layer surface by a roughening treatment, wherein the average roughness Rz of TD of the roughening-treated surface of the ultrathin copper layer is 0.20 to 0.80μm, the 60-degree glossiness of MD of the roughening-treated surface is 76 to 350% and the ratio A/B between the surface area A of the roughened particles and the surface area B obtained when the roughened particles are planarly viewed from the surface side of the copper foil is 1.90 to 2.40.
