<p>A sealing member comprising an elastic sheet having a density in the range of 100 to 250 kg/m 3 . The elastic sheet is obtained by reacting and curing a polyurethane-foam raw material which is provided by mixing 100% by volume of a resin raw material and 300% by volume or more of a foam-forming gas, in which the resin raw material includes polyol and isocyanate as a main raw material and a foam stabilizer as an auxiliary material, and the like. The compression load deflection at 50% of the elastic sheet is in the range of 0.003 to 0.025 MPa, and the compression load deflection at 75% thereof is in the range of 0.02 to 0.40 MPa.</p> |
