An object of the present invention is to provide a foam molding which is light, excellent in bending strength, and excellent in balance between compressive strength and com- pression permanent strain, being a foam in which thermoplas- tic resin high expanded foams whose overall outer surfaces are covered with thermoplastic resin low-expanded-foam thin layers are thermally fused with each other through the aforementioned low-expanded-foam thin layers.

Article expansé, moulé, de faible poids et présentant une résistance à la flexion élevée, une résistance à la compression équilibrée exceptionnelles et une excellente propriété de déformation permanente sous pression. Ladite mousse comprend une résine thermoplastique hautement expansée dont la surface externe est intégralement recouverte d'une feuille mince faiblement expansée de résine thermoplastique, et fusionnée thermiquement par l'intermédiaire de ladite feuille à une autre résine hautement expansée.
