To provide an environment-friendly wall paper having high stain resistance and scratch resistance, and a manufacturing method thereof.SOLUTION: A wall paper 10 is formed by sequentially stacking a paper substrate 11, a foam resin layer 12 containing at least resin component, foaming agent, and filler, a pattern layer 13 having printed picture pattern, and a surface film layer 14 of ethylene-vinyl alcohol copolymer. A non-vinyl chloride resin containing at least either one of ethylene-vinyl acetate copolymer and ethylene-unsaturated carboxylic acid copolymer is used for the foam resin layer 12. The basis weight of the foam resin layer 12 is set to 80 g/m2 or more and 100 g/m2 or less. Weighing amount of the paper substrate 11 may be set to 50 g/m2 or more and 70 g/m2 or less. Addition amount of the foaming agent may be set to 5 parts by weight or more and 20 parts by weight or less with respect to 100 parts by weight of resin component of the foam resin layer 12.SELECTED DRAWING: Figure 1 【課題】環境に配慮した、耐汚染性・耐傷性の高い壁紙及びその製造方法を提供する。【解決手段】紙基材１１と、樹脂成分、発泡剤及び充填剤を少なくとも含有する発泡樹脂層１２と、印刷による絵柄模様を有する絵柄層１３と、エチレン・ビニルアルコール共重合体の表面フィルム層１４と、が順次積層されている壁紙１０であって、発泡樹脂層１２には、エチレン−酢酸ビニル共重合体と、エチレン−不飽和カルボン酸共重合体との少なくとも一方の樹脂を含有する非塩ビ系の樹脂を使用し、発泡樹脂層１２の坪量を、８０ｇ／ｍ2以上１００ｇ／ｍ2以下に設定する。紙基材１１の秤量を、５０ｇ／ｍ2以上７０ｇ／ｍ2以下に設定しても良いし、発泡剤の添加量が、発泡樹脂層１２の樹脂成分１００質量部に対し、５質量部以上２０質量部以下としても良い。【選択図】図１
