ものとなる。As described above, according to the constitution of the present invention, since halogen elements are not contained unlike vinyl chloride resin, there is no problem at the time of incineration, and when the molten olefinic foamed resin is cooled in the manufacturing method. Since embossing is applied at the same time, reproducibility of embossing is good. Moreover, since the transparent thermoplastic resin layer is provided on the surface and the pattern layer is provided on the inner layer, the stain resistance is excellent even without forming a protective coating film on the surface as in the conventional case. Furthermore, since the three layers can be bonded at the same time and the processes such as foaming, embossing, bonding, and cooling can be performed in a small number of steps, the product can be manufactured at low cost.
