Abstract: Provided is a method of preparing a metal laminate-polymer resin composite including a metal laminate formed of copper and aluminum laminated therein; and a polymer resin. According to an embodiment of the present disclosure, the method includes an electrolytic oxidation step of electrolytically oxidizing the metal laminate in a solution for electrolytic oxidation to form a first porous oxide film having a roughened structure on a surface of the aluminum; an electroless oxidation step of performing electroless oxidation for the metal laminate in a solution for electroless oxidation to form a second porous oxide film having a roughened structure on a surface of the copper; and a bonding step of bonding the metal laminate with the polymer resin.
