Zusammenfassung:	To provide a protective sheet including a protective layer that is relatively easily removed by a water-containing liquid and has not only good adhesion to an object to be protected but also good processability.SOLUTION: The protective sheet includes a protective layer that is removed by a water-containing liquid after protecting at least a portion of the surface of an object to be protected. The protective layer includes a solid hydrophilic polymer and a liquid compound containing a hydrophilic group in the molecule.SELECTED DRAWING: Figure 1 【課題】水を含む液体によって比較的簡便に除去され、保護対象物への密着性が良好であるだけでなく、加工性が良好な保護層を備える保護シートを提供することを課題としている。【解決手段】保護対象物の表面の少なくとも一部を保護した後に、水を含む液体によって除去される保護層を備え、前記保護層は、固体状の親水性ポリマーと、分子中に親水基を含有する液状の化合物とを含む、保護シートを提供する。【選択図】図１
