Adhesive (not shown), etc. is attached to the floor material main body made by laminating the damping material and the surface material on the plywood so that the multiple layers of urethane foam sheets are located on the side opposite to the floor material main body. The floor material for soundproofing is formed. Therefore, since the ground contact surface is hard and the top surface is softer than the ground contact surface side, when walking, the load is firmly received and the walking feeling is stable. In addition, the presence of polyurethane foam sheets with different hardness improves sound absorption.

上する。The thermal compression polyurethane foam sheet 25 thus formed is obtained by heating and compressing a laminate of a high hardness soft urethane foam sheet 21 and a semi-rigid urethane foam sheet 22 laminated with an adhesive 23. Thus, the unevenness pattern 24 is formed on both surfaces of this laminated body. The heat-compressed polyurethane foam sheet 25 having such a structure is formed on the plywood 26 as shown in FIG.
7, a floor material main body 29 formed by laminating surface materials 28 is adhered with an adhesive (not shown) so that the high-hardness soft urethane foam sheet 21 is located on the side opposite to the floor material main body 29 for soundproofing. A floor material 30 is formed (shown in FIG. 3). Therefore, since the ground contact surface is hard and the top surface is softer than the ground contact surface side, when walking, the load is firmly received and the walking feeling is stable. Further, the presence of the polyurethane foam sheets 25 and 21 having different hardness improves sound absorption.
