The present invention provides a foamed urethane sheet which is formed from an aqueous urethane resin composition containing a urethane resin (A), an aqueous medium (B), and a surfactant (C) having 10 or more carbon atoms, and has a density of 200 to 1,000 kg/m 3 . Further, the present invention provides a synthetic leather having at least a substrate (i) and a polyurethane layer (ii), wherein the polyurethane layer (ii) is formed from the foamed urethane sheet according to any one of claims 1 to 4 . The polyurethane layer (ii) may be embossed. The surfactant (C) is preferably a stearic acid salt, and the urethane resin (A) which has an anionic group, and has a flow starting temperature of 80° C. or higher is preferably used. |
