The present invention provides a floor covering which is excellent in surface properties such as heat insulation, water resistance, moisture resistance, shape stability, impact resistance, load resistance and damage resistance, and which is also excellent in ease of construction. The floor decoration material has a foamed resin layer, a support layer and a decorative layer in sequence, the foamed resin layer has a foaming ratio of 5 to 20 times, and a compressive elastic modulus of 20 MPa or more, and the support layer has a tensile elasticity of 5 to 20 times. The modulus is 180 MPa or more. |
