Abstract: A method for producing an ink-jet head includes forming a buffer layer on an upper surface of a vibration plate, and forming a piezoelectric precursor layer on an entire upper surface of a surface layer, the piezoelectric precursor layer being converted into a piezoelectric sheet. The buffer layer is formed of a material with which mutual diffusion between the piezoelectric precursor layer and the buffer layer is hardly caused as compared with mutual diffusion between the piezoelectric precursor layer and the vibration plate with which no buffer layer is provided. A stack, in which the buffer layer and the piezoelectric precursor layer are formed, is heated at a predetermined temperature, and the piezoelectric precursor layer is calcinated to form the piezoelectric sheet. It is possible to suppress the deterioration of the performance of the piezoelectric member.
