Beschreibung
Zusammenfassung:	An object of the present invention is to provide an IGZO sputtering target capable of improving uniformity for at least one property selected from the number of microcracks in the structure, the number of pores in the sintered body structure, and surface roughness.The IGZO sputtering target according to the present invention has an oxide sintered body, the oxide sintered body comprising indium (In), gallium (Ga), zinc (Zn) and unavoidable impurities, wherein, on a surface of the oxide sintered body, a lightness difference ΔL* satisfies ΔL*
