PROBLEM TO BE SOLVED: To provide a metal-clad laminated sheet excellent in dielectric characteristics, and a printed wiring board using the same. SOLUTION: In the metal clad laminated sheet wherein a metal foil is provided on the surface of a laminated sheet which is obtained by laminating prepregs, each of which is formed by impregnating glass cloth with an electric insulating resin composition to dry the impregnated glass cloth, to integrally mold them, an electric insulating resin composition layer having at least one of a dielectric constant and dielectric loss tangent lower than that of the above mentioned electric insulating resin composition is formed in contact with the metal foil. The printed wiring board using the same is also disclosed. |
