This study aims to clarify the influence of surface topography on the photocatalytic function of TiO_2 film surface to support the manufacturing high-performance photocatalytic films. In this report, a few textured TiO_2 film surfaces were produced by conducting the anodic oxidation to the titanium plates with micro cutting grooves under various cutting conditions, and the wettabilty which is one of the photocatalytic functions was evaluated. As a result, it is understood that the wettability of manufactured TiO_2 film is improved with increasing the real surface area, and it is also confirmed that the high-performance TiO_2 films can be manufactured by combination of the microcutting and anodic oxidation, even though further increase in the real surface area is necessary.
