ABSTRACT:
The target for the transparent conductive thin film having indium oxide as its major component and containing tungsten and/or molybdenum, obtained by forming a body of indium oxide powder, and tungsten oxide power and/or molybdenum oxide powder and then heating or sintering the formed body such that the thin film after sputtering has indium oxide as the main component and contains tungsten and/or molybdenum with an atomic ratio (W+Mo)/In of 0.0040 to 0.0470, whereby a transparent conductive thin film having excellent surface smoothness and low specific resistance of 6.0×10−4Ω·cm or less, and whose surface smoothness and specific resistance properties do not change even when heated at 170° C. is provided.
