PROBLEM TO BE SOLVED: To provide a foamed wallpaper capable of preventing a foaming agent from being thermally decomposed in an extruder.SOLUTION: A foamed wallpaper 1 includes a foamed layer 3 made of foamed resin layer containing a foaming agent that contains a supercritical fluid, and a paper substrate 2 laminated to the foamed layer 3. The use of supercritical fluid as foaming agent can prevent the thermal decomposition of foaming agent in an extruder, differentiating from, for example, a method using a thermally decomposable agent.SELECTED DRAWING: Figure 1 【課題】本発明は、押出機内での発泡剤の熱分解を防止可能な発泡壁紙を提供可能とすることを目的とする。【解決手段】発泡壁紙１は、超臨界流体を含有する発泡剤含有樹脂層が発泡した発泡層３と、発泡層３に貼り合わされた紙基材２とを有する。このように、超臨界流体を発泡剤として用いているため、例えば、熱分解発泡剤を用いる方法と異なり、押出機内での発泡剤の熱分解を防止することができる。【選択図】 図１
