The invention provides an adhesive layer-attached conductive foil and a conductor-clad laminated sheet which allow transmission loss to be satisfactorily reduced especially in the high-frequency band, which exhibit excellent heat resistance, and which allow production of printed circuit boards that are adequately resistant to interlayer peeling. The adhesive layer-attached conductive foil of the invention is provided with a conductive foil and an adhesive layer formed on the conductive foil, wherein the adhesive layer is composed of a curable resin composition containing component (A): a polyfunctional epoxy resin, component (B): a polyfunctional phenol resin and component (C): a polyamideimide. The conductor-clad laminated sheet of the invention comprises an insulating layer, a conductive layer situated facing the insulating layer, and an adhesive layer sandwiched between the insulating layer and conductive layer, and the adhesive layer is composed of a cured resin composition containing components (A), (B) and (C).
