To provide a double-sided metal clad laminate reducing warping thereof.

The double-sided metal clad laminate is formed by laminating metal foils 3 having different thickness on both surfaces of an insulating layer 2 which has a base material 1 therein. A difference between a distance D1 between a thick metal foil 3a and the base material 1 and a distance D2 between a thin metal foil 3b and the base material 1 is at least one half of the difference between thicknesses of the metal foils 3 of both surfaces.
