To provide a method of manufacturing a two-layer copper clad laminated sheet which can further inhibit oxidation discoloration after a heat treatment which raises folding resistance in the two-layer copper clad laminated sheet (two-layer CCL material) wherein a copper layer is formed on a polyimide film by sputtering and plating, and to provide the two-layer copper clad laminated sheet.

The two-layer copper clad laminated sheet is obtained by forming a metal layer of one selected from Ni, Co, and Cr or an alloy layer consisting of two or more of them on a polyimide film by sputtering; forming a copper layer on the metal layer or the alloy layer by sputtering or plating; and further forming a layer consisting of Cr and/or Cr oxide on the copper layer.
