PROBLEM TO BE SOLVED: To perform the joining of a photocatalyst resin film, which is carried out through thermal welding after a photocatalyst layer is shaved off, without damaging a base material.SOLUTION: A photocatalyst resin film material 100 includes a base material 10 prepared by weaving threads and a resin layer 20 covering both surfaces of the base material 10, and further includes a photocatalyst layer 60, an adhesion layer 50 and a plasticizer migration prevention layer 40 on one surface of the resin layer 20. Further, the photocatalyst resin film material 100 has a relatively thick second resin layer 30, formed by laminating resin films, between the plasticizer migration prevention layer 40 and the resin layer 20. Thereby, even when the photocatalyst layer 60 is shaved off, the threads in the base material 10 are prevented from being damaged. |
