The invention aims to provide a resin primer which can stick an insulator layer to a conductor foil whereof the surface is not much roughened with sufficient adhesive force, a conductor foil with resin, a laminated sheet and a method of manufacturing same. The resin primer of the invention comprises a resin having film-forming ability and a breaking energy of 0.15 J or more. The conductor foil with resin of the invention comprises a resin layer comprising a conductor foil and the aforesaid resin primer. Further, the laminated sheet of the invention comprises the conductor foil, an insulating layer disposed facing the conductor foil, and a resin layer comprising the aforesaid resin primer disposed between the conductor foil and insulating layer so that it is in contact therewith. This laminated sheet can be manufactured by heating and pressurizing a laminate comprising the aforesaid conductor foil with resin, and a prepreg laminated on this resin layer.
