PROBLEM TO BE SOLVED: To quarantee an excellent air purification efficiency for a long period of time by providing a mesh-like protective sheet additively along a mesh-like photocatalytic sheet wherein a photocatalytic particle-containing resin layer is provided to a surface of a mesh-like support base material or a bending formed body of the mesh-like photocatalytic sheet. SOLUTION: A photocatalytic particle-containing polytetrafluoroethylene burnt layer is provided to a surface of a mesh-like support base material such as, for example, a plain weave glass cloth or the like to obtain a mesh-like photocatalytic sheet 1. In order to obtain a ventilating photocatalytic sheet structured body A or B or C from the mesh-like photocatalytic sheet 1, for example, the mesh-like photocatalytic sheet 1 is formed by bending in a cylindrical body (a bellows body) 10, and the formed body 10 is covered by a mesh-like protective sheet 2 (the structured body A, C), or the mesh-like protective sheet 2 is piled up on a side surface of the mesh-like photocatalytic sheet 1 (the structured body B). As the mesh-like protective sheet 2, excepting a metal-made net and a resin-made net, a woven fabric, a nonwoven fabric, or the like of a synthetic resin fiber or the like are used. |
