Abstract: A structural member 10 includes a base material 100 and a protective film 200 covering a surface 101 of the base material 100. At least a portion of the protective film 200 in the vicinity of a surface 201 thereof has a first layer 210 and a second layer 220 that contains all of elements contained in the first layer 210 and that is different from the first layer 210 in composition ratio of each element, wherein the first layer 210 and the second layer 220 are alternately aligned along a depth direction perpendicular to the surface 201 of the protective film 200.

Abstract: Provided by the present invention is a photocatalytic coating composition which can express excellent visibility during application work and further can, owing to its excellent physical properties, form a homogeneous photocatalyst coated film having uniform thickness on a surface of a substrate. The photocatalytic coating composition which is basic and comprises photocatalyst particles, a basic dye, a layered silicate, and a dispersion medium. The basic dye enhances visibility of the part where the photocatalytic coating composition is applied so that the applied part can be easily distinguished from the unapplied part by the difference in appearance. After application work, color of the basic dye disappears by photolysis with a solar light or by decomposition with a photocatalyst. The layered silicate suppresses color change of the basic dye over time and stably keep color tone of the same.
