Abstract
A transparent conductive zinc oxide based film according to the present invention contains Ti, Al and Zn in such a proportion that satisfies the following formulae (1), (2) and (3) in terms of atomic ratio, and has a plurality of surface textures different in size on a surface, wherein a center-line average surface roughness Ra of the surface of the transparent conductive film is 30 nm to 200 nm, and an average value of widths of the surface textures is 100 nm to 10 μm.0.001≦Ti/(Zn+Al+Ti)≦0.079.  (1)0.001≦Al/(Zn+Al+Ti)≦0.079  (2)0.010≦(Ti+Al)/(Zn+Al+Ti)≦0.080  (3)
