<p>Provided is a suitably firm and lightweight mat having excellent thermal insulation properties, flame resistance, and sound absorbency. Besides, it is possible to use disposed materials for the mat. A ground product of resin foam (15), consisting of a moisture curing isocyanate compound adhering to a ground product of resin foam containing 10 wt% or more of a ground product of melamine resin foam, is placed in a metal mold (70). By curing the moisture curing isocyanate compound adhering to the ground product of resin foam with moisture, the ground product of resin foam is bonded to form a mat (11) with a density of 23-110 kg/m3 inclusive.</p> |
