PROBLEM TO BE SOLVED: To provide a laminate sheet formed with a microfiber layer on a substrate, which has high adhesion to the substrate and is excellent in air-permeability, and to provide a method for producing the sheet. SOLUTION: The method for producing a laminate sheet comprises laminating a microfiber layer by electrostatic spraying of a microfiber material solution obtained by liquifying the microfiber component using a solvent, wherein the method comprises a step for forming an intermediate layer 3 which is composed of a first fiber diameter of the microfiber on the resin-based substrate 2 by the first electrostatic spraying, and a step for forming a surface layer 4 which is composed of microfibers comprising a second fiber diameter less than the first fiber diameter on the intermediate layer 3 by the second electrostatic spraying.
