To provide a waterproof sheet with excellent long term weather resistance and long term durability.SOLUTION: A waterproof sheet 10 comprises a laminate of a plurality of layers including a polyvinyl chloride resin, a plasticizer, and an inorganic particle. The laminate includes a rear face layer 12 at a construction face side and a surface layer 16. The ash concentration in the rear face layer 12 is higher than that in the surface layer 16. The ash concentration in each of the plurality of layers is different from one another.SELECTED DRAWING: Figure 1
【課題】長期耐候性、長期耐久性に優れた防水シートの提供。【解決手段】ポリ塩化ビニル樹脂と、可塑剤と、無機粒子と、を含む複数層の積層体からなり、積層体は、施工面側の裏面層１２と、表面層１６と、を含み、裏面層１２の灰分濃度が表面層の１６灰分濃度より高い、複数層毎に灰分濃度が異なる防水シート１０。【選択図】図１
