PROBLEM TO BE SOLVED: To provide a wound covering material that can form a wet environment necessary for growth of epidermal cells as well as can suppress pH rise in the wound surface due to elution of alkaline components and in addition can elute wound healing components and antibacterial components.SOLUTION: Provided is a wound covering material having a gel layer 1 and a support layer 2 comprising a glass fiber nonwoven fabric, and in which the gel layer 1 is made of a water-soluble or hydrophilic polymer having an acidic functional group and has a first surface 1a in contact with the wound surface and a second surface 1b opposing the first surface 1a, and the support layer 2 comprises a glass containing, as a glass composition, B2O3 and CaO as well as is formed on a second surface 1b of the gel layer.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】表皮細胞の増殖に必要な湿潤環境を形成するとともに、アルカリ成分の溶出による創面のpH上昇を抑制し、しかも創傷治癒成分及び抗菌性成分を溶出可能な創傷被覆材を提供。【解決手段】ゲル層1と、ガラス繊維不織布を含む支持層2とを有し、ゲル層1は、酸性官能基を有する水溶性又は親水性の高分子からなるとともに、創面に接する第一の表面1aと、第一の表面1aに対抗する第二の表面1bとを有し、支持層2は、ガラス組成としてB2O3とCaOを含有するガラスからなるとともに、ゲル層の第二の表面1b上に形成される創傷被覆材。【選択図】図1
