A method for producing a coagulated article includes coagulating an aqueous urethane resin composition with a coagulant containing a metal salt and water and being heated to 40° C. or higher. A coagulated article having excellent texture can be obtained without using an organic solvent. Further, an organic solvent is not used for a coagulating bath, and therefore there is no fear of exposure to a harmful volatile substance or diffusion of the substance into the environment, and further the treatment of waste liquid of such a coagulating bath is easy, which contributes to suppression of the cost of production. Therefore, a coagulated article obtained by the method can be advantageously used in producing gloves, a coating material, a simulated leather sheet, and the like.
