Abstract
An oxide sintered body has metal elements of In, Ga, Zn, and Sn and contains GaInSnO, ZnGaO, and InGaZnO. The contents of In, Ga, Zn, and Sn in the oxide sintered body satisfy the relations [Ga]≥37 atomic %, [Sn]≤15 atomic %, and [Ga]/([In]+[Zn])≥0.7, where [In], [Ga], [Zn], and [Sn] represent ratios (atomic %) of In, Ga, Zn, and Sn with respect to all metal elements contained in the oxide sintered body, respectively.
