Abstract
An oxide sintered body is obtained by mixing and sintering a zinc oxide, an indium oxide, a gallium oxide and a tin oxide. The oxide sintered body has a relative density of 85% or more, and has volume ratios satisfying the following expressions (1) to (3), respectively, as determined by X•ray diffractometry: (1) (ZnSnOphase+InGaZnOphase)/(ZnSnOphase+InGaZnOphase+InOphase+SnOphase+(ZnO)InO, phase)≧75% by volume; (2) ZnSnOphase/(ZnSnOphase+InGaZnOphase+InOphase+SnOphase+(ZnO)InOphase)≧30% by volume; and (3) InGaZnOphase/(ZnSnOphase+InGaZnOphase+InOphase+SnOphase+(ZnO)InOphase)≧10% by volume, and m represents an integer of 2 to 5.
