The present invention is to provide a method for manufacturing synthetic leather in which, after obtaining a thickened liquid by adding a thickening agent (B) with an oxyethylene group content of 2×10.sup.−2 mol/g or less to an aqueous urethane resin composition containing an aqueous urethane resin (A) having an acid value of 0.01 mgKOH/g or higher in a range of 0.01 to 30 parts by mass relative to 100 parts by mass of the aqueous urethane resin (A), the thickened liquid is coated on a base and coagulated with a coagulating agent (C) containing a metal salt (c-1). As the thickening agent, it is preferable to use one or more kinds of thickening agent that is selected from the group consisting of a cellulose thickening agent, an acryl thickening agent, and a urethane thickening agent. Furthermore, as the metal salt (c-1), calcium nitrate is preferable.
