Abstract: Provided are a barium germanium oxide having a 3-4 eV band gap, a method for producing the same, a sintered body thereof, and a target thereof. The barium germanium oxide includes at least Ba, Ge, and O, includes a crystal represented by a general formula of ABO3 (here, A includes at least Ba and B includes at least Ge), and has a hexagonal 6H-type perovskite structure.
