摘要

Provided is a titanium oxide laminated film that includes the titanium oxide film consisting of anatase-type plate-like crystals in which (001) faces with a high chemical activity are grown more than normal and the (001) faces are grown in a vertical or inclined direction with respect to a deposition surface of a base material, and is capable of having a specific surface area greater than that of the titanium oxide film alone. A titanium oxide laminated film (1) is formed by sequentially laminating, on a base material (11), a first titanium oxide film (12) consisting of a plurality of anatase-type plate-like crystals in which (001) faces are grown in a vertical or inclined direction with respect to a deposition surface (11a) of the base material (11), and a second titanium oxide film (13) having a specific surface area greater than that of the first titanium oxide film (12) and consisting of a plurality of titanium oxide fine particles.
