There is provided a copper foil with an insulating adhesive which is excellent in that an insulating adhesive layer has low dieletric constant, low dieletric loss tangent and high adhering force at a normal temperature and a high temperature, and steps for manufacturing a multilayer printed circuit board can be shortened due to the presence of a copper foil on which a circuit can be formed by etching or the like. An insulating adhesive composition containing as an essential component an organic compound having at least two alkenyl groups having the reactivity with a SiH group in one molecule, and a silicon compound containing at least two SiH groups in one molecule and a copper foil are incorporated.
