A metal-clad laminate of the present invention comprises an insulating layer, and a metal layer that is present at least on one surface side of the insulating layer. The insulating layer is a laminate of at least three layers: a center layer, a first resin layer that is present on one surface side of the center layer, and a second resin layer that is present on the other surface side of the center layer. The center layer, the first resin layer and the second resin layer each contain a cured product of a respective resin composition. The elastic modulus of the cured product of the resin composition contained in the center layer is lower than the elastic moduli of both the cured product of the resin composition contained in the first resin layer and the cured product of the resin composition contained in the second resin layer.
