PROBLEM TO BE SOLVED: To provide a light-shielding material for photodynamic treatment that reliably provides care by photodynamic treatment (PDT) to improve safety of PDT.SOLUTION: A light-shielding material for photodynamic treatment includes: a water absorptive first member 11 a light-shielding second member 12 and a third member 13 for shielding at least part of light reflected from the second member 12. The first member 11, the second member 12 and the third member 13 have a substantially same shape. The first member 11, the second member 12 and the third member 13 are laminated in this order.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】PDTによる治療を確実に行い、PDTの安全性を向上させることができる光線力学的療法用遮光材を提供する。【解決手段】吸水性を有する第1の部材11と、遮光性を有する第2の部材12と、第2の部材12で反射した光の少なくとも一部を遮光する第3の部材13とを有する。第1の部材11、第2の部材12、および第3の部材13は略同一形状を有し、第1の部材11、第2の部材12、第3の部材13の順に積層された。【選択図】図1
