Zusammenfassung:PROBLEM TO BE SOLVED: To provide a copper foil with a fiber-reinforced resin suitable to form a thin insulation layer excellent in reliability and its manufacturing method. SOLUTION: The manufacturing method of the copper foil with fiber-reinforced resin comprises the steps of forming a resin layer on a copper foil and burying a fiber into the resin after making the fiber adhere to this resin layer by an electrostatic force. As the more preferred method, the manufacturing method of the copper foil with fiber-reinforced resin comprises the steps of forming the first resin layer on the copper foil, solidifying the first resin layer after making the fiber adhere by electrostatic force in the condition that this first resin layer is not solidified, and forming the second resin layer on it to make the fiber buried into the resin layer.
