PROBLEM TO BE SOLVED: To provide a laminated body for a flexible printed wiring board that comprises a conductor layer formed on a resin film, has an excellent etching characteristic and excellent adhesion between the resin film and the conductor layer, which are particularly held even after a durability test, and thereby has superior reliability. SOLUTION: In the laminated body for a flexible printed wiring board, a copper alloy layer that contains 0.1 to 10.0 atom% of Mg and/or Si is formed on a resin film. The copper alloy layer containing 0.1 to 10.0 atom% of Mg and/or Si is formed on the resin film, and a copper sputter layer and/or a copper plating layer are/is formed on the copper alloy layer.
