PROBLEM TO BE SOLVED: To provide a method for producing a new polyurethane synthetic leather by which a pollution level is decreased, production efficiency is improved and a production cost is decreased. SOLUTION: This method for producing a polyurethane synthetic leather comprises (a) a step for forming a film layer by using a polyurethane selected from a granular hot-melt type polyurethane, a ultraviolet-hardenable polyurethane, a multi-solvent type polyurethane, a single solvent type polyurethane, an aqueous polyurethane and a moisture-hardenable polyurethane, (b) a step for applying the moisture-hardenable polyurethane on the film layer or a substrate layer as an adhesive layer, and (c) sticking the substrate layer or the film layer to the adhesive layer.
