An oxide semiconductor film having crystallinity includes indium (In) and a first metal element (M1) selected from the group consisting of aluminum (Al), gallium (Ga), yttrium (Y), scandium (Sc), and lanthanoid elements. A crystal structure of the oxide semiconductor film is a bixbyite structure. At least a first peak of a (222) plane and a second peak of a (440) plane are observed in a diffraction pattern of the oxide semiconductor film obtained by an out-of-plane XRD measurement using Cu-Kα radiation. A ratio of an intensity of the first peak to an intensity of the second peak is less than or equal to 125.
