Zusammenfassung:	To provide a concrete curing sheet being highly effective in curing, excellent in adhesiveness to concrete, and easy to remove, and a method of curing the concrete.SOLUTION: A concrete curing sheet of this invention, in which a substrate layer and a surface layer are laminated, has water vapor permeability of 0.01-2.5 g mm/(m24hr). The substrate layer is a thermoplastic film and the surface layer containing filler is a porous polyolefin resin film including openings in the surface. An opening ratio of the surface of the surface layer is 6-60%.SELECTED DRAWING: Figure 1 【課題】養生効果が高く、コンクリートとの接着性が良好であって、かつ除去が容易なコンクリートの養生シート及び養生方法を提供する。【解決手段】コンクリートの養生シートは、基材層と表面層とが積層されたコンクリートの養生シートであって、前記養生シートの水蒸気透過係数が、０．０１〜２．５ｇ・ｍｍ／（ｍ２・２４ｈｒ）であり、前記基材層が熱可塑性樹脂フィルムであり、前記表面層が、フィラーを含有し、表面に開口を有する多孔性のポリオレフィン系樹脂フィルムであり、前記表面層の表面の開口率が、６〜６０％である。【選択図】図１
