To provide a foamed molded product which is not elastically deformed while maintaining its gas permeability, and to provide a method for producing the same.
The method for producing a foamed molded product formed by subjecting natural rubber and/or synthetic rubber latex to foam molding comprises: a mixing step where natural rubber and/or synthetic rubber latex is at least blended with a foaming agent, a vulcanizing agent and a vulcanization accelerator, and is further mixed with an aqueous one-liquid type oil modified polyurethane resin paint of 0.5 to 50 pts.mass based on the total mass of the natural rubber and/or synthetic rubber latex; a foaming step where the mixture obtained in the above step is foamed; a gelling step where the one foamed in the above step is mixed with a gelling agent, and the gelled matter is cast onto a supporting fabric; a vulcanizing step where the sheet obtained in the above step is heated and vulcanized; and a molding step where the sheet is heated and molded in a die having a cavity corresponding to the shape of the foamed molded body at a temperature equal to or higher than the softening point of the aqueous one-liquid type oil modified polyurethane resin paint.
