PROBLEM TO BE SOLVED: To provide an insulation sheet with a metal foil whose cured insulation layer has high rigidity, capable of simplifying lamination work for making a multilayered board, and making the multilayered board using a metal foil without a carrier even if the thickness of the metal foil is not greater than 9μm. SOLUTION: The insulation sheet 1 with the metal foil is formed by joining integrally an insulation layer 2 with a metal foil 3 wherein the insulation layer 2 comprises a glass woven fabric 4 and a thermosetting resin 5 in a B stage state.
