PROBLEM TO BE SOLVED: To provide a method for preparing perovskite type oxide powder capable of preventing from lowering and fluctuating the performance of a sintered compact in production lots. SOLUTION: In the producing method of the perovskite type oxide generally described as ABO3 in a chemical formula, starting raw materials are prepared that the molar ratio between A and B is denoted as 1<B/A<1.3, the specific surface area is 3-15 m<2> /g and the median diameter of the particles is 1 μm or less. |
