    • There is disclosed an elastic member constituted of polyurethane foam obtained by agitationally mixing with water, a urethane prepolymer synthesized from a polyol and a polyisocyanate, characterized by simultaneously employing as polyols, a (A) polymer polyol synthesized from a polyether polyol as a basis, comprising at least 70% by weight of oxypropylene moiety; and a (B) hydrophilic polyether polyol comprising at least 50% by weight of oxyethylene moiety, or simultaneously employing as polyols, the component (A), the component (B) and a (C) polyether polyol comprising at least 70% by weight of oxypropylene moiety. The above elastic member is simultaneously imparted with excellent characteristics such as low hardness, fine cells, low residual compressive strain, high strength and the like. The polyurethane foam which constitutes the elastic member can be produced by free foaming. The electroconductive elastic member which is produced by using an aqueous dispersion of carbon instead of water is imparted with low electric resistance in addition to the above excellent characteristics.
