The invention provides an oxide sintered compact 2 composed of a crystal phase which consists of a bixbite-type oxide phase and a perovskite-type oxide phase, or a bixbite-type oxide phase, the crystal phase having indium, tin, strontium and oxygen as the constituent elements, and the indium, the tin and the strontium contents satisfying formulas (1) and (2) in terms of atomic ratio, as well as a sputtering target. There are further provided an oxide transparent conductive film formed using the sputtering target, and a solar cell. Sn/(In+Sn+Sr)=0.01-0.11  (1) Sr/(In+Sn+Sr)=0.0005-0.004  (2) [In formulas (1) and (2), In, Sn and Sr represent indium, tin and strontium contents (atomic percent), respectively.]
