PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal-clad laminate difficult to generate a void in the method for manufacturing the metal-clad laminate comprising the steps of current supplying a metal foil, and molding the foil by resistance heating. SOLUTION: The method for manufacturing the metal-clad laminate comprises the steps of pressing an element 5 formed by alternately disposing laminates 5 each obtained by disposing prepregs 2 each obtained by impregnating a base with a thermosetting resin between the metal foils 1 and molding plates 3, current supplying to the foils 1, heating the laminates 5 by resistance heating, and pressurizing the laminates 5. The method further comprises the steps of molding the laminates in an atmospheric pressure of a reduced pressure of a range of 1333 to 6665 Pa from a heating starting time point, and releasing the pressure reduction of the atmospheric pressure when a temperature of the laminate 5 becomes a temperature or lower by 20 to 10 deg.C than a glass transition temperature of the prepreg 2.
