Abstract:
1. An oxide film, which is obtained by a sputtering method by using an oxide sintered body which comprises gallium, indium, and oxygen, with a content of the gallium being more than 65 at. % and less than 100 at. % with respect to all metallic elements, the oxide sintered body having one or more phases selected from a gallium oxide phase having β-Ga the oxide sintered body having an indium oxide phase (In wherein a ratio in which the indium oxide phase (In and which has a density being 5.0 g/cm wherein the oxide film comprises gallium, indium and oxygen, with a content of the gallium being more than 65 at. % and less than 100 at. % with respect to all metallic elements, and a shortest wavelength at which light transmittance of the film itself, excluding a substrate, becomes 50% is 320 nm or less:
