Concerning the ferroelectric films produced by AD method, the effects by adding auxiliary agents to injection powder and the effects by grain size were investigated for the purpose of realizing higher ferroelectric property. Ferroelectricity of AD film was found to be improved by adding low melting point auxiliary agents and using calcined powder, and was also found to depend on the grain size of injection powder, and to be improved by increasing the size to an appropriate value. By optimizing the conditions, good ferroelectricity was realized; such as Pr = 25.4 micro C/cm2 in the heat treatment at 600°C (63% of sintered film, calcined powder added with low melting point glass) and Pr = 38.0 micro C/cm2 in the heat treatment at 700°C (95% of sintered film, calcined powder added with Bi2O3-ZnO).
