摘要:
A hydrophilic member that enables provision of favorable photocatalytic performance while enhancing water repellent agent resistance and a method for manufacturing the same are provided. A maintenance method for removing a water repellent agent adhering to a surface of a hydrophilic layer of a hydrophilic member, the water repellent agent having a cation property, is provided. A photocatalytic layer is formed on a base material. An intermediate layer is formed on the photocatalytic layer. A hydrophilic layer having an isoelectric point exceeding 7 is formed on the intermediate layer. The intermediate layer is a layer that causes the hydrophilic layer to be formed so as to have a low density compared to a case where the hydrophilic layer is formed directly on the photocatalytic layer under the same film forming condition. A water repellent agent adhering to a surface of the hydrophilic layer can effectively be removed using sodium bicarbonate.
