Summary:本发明提供一种具有良好特性的强电介质膜的制造方法和利用该制造方法来获得的强电介质膜。本发明的强电介质膜的制造方法是将含有复合氧化物的原材料体进行结晶化的工序包括在内的强电介质膜的制造方法；包括：(a)在所定压力和温度的第一状态中，进行热处理；(b)在所述(a)工序之后，维持在低于或等于第一状态的压力和温度的第二状态的工序；并重复进行所述(a)和(b)的方法进行结晶化。 A method of manufacturing a ferroelectric film having excellent characteristics and a ferroelectric film manufactured by this method are provided. This method of manufacturing a ferroelectric film includes crystallizing a raw material having a complex oxide, the method including: performing a heat treatment in a first condition in which a predetermined pressure and a predetermined temperature are applied; and maintaining a second condition, in which a pressure and a temperature lower than the pressure and the temperature in the first condition are applied, after the heat treatment in the first condition, and the raw material is crystallized by repeating the heat treatment in the first condition and the maintaining the second condition.
