PROBLEM TO BE SOLVED: To provide a single-sided flexible metal laminated sheet reduced in warpage. SOLUTION: The single sided flexible metal laminated sheet is constituted by laminating a metal layer to one side of a heat-resistant adhesive film wherein thermoplastic resin layers are provided on both sides of a non-thermoplastic film and characterized in that the humidity expansion coefficient A (ppm/% RH) of the thermoplastic resin layer (a) on the metal layer side of the heat-resistant adhesive film and the humidity expansion coefficient B (ppm/% RH) of the other thermoplastic resin layer (b) satisfy the formula: 3≤A-B≤15(ppm/% RH).
