Preparation of the laminated piezoelectric element

According to the present invention, there are provided a stack-type piezoelectric element constructed of a stacked body comprising plural layers (1) of sintered piezoelectric ceramic material and electrodes (2, 3) which lie between the respective layers (1, 1) of the piezoelectric ceramic material, wherein said electrodes (2, 3) are formed of a material capable of diffusion-bonding with said piezoelectric ceramic material at a lower temperature than the sintering temperature of said ceramic material, a process for producing the same, and a stack-type piezoelectric device using said stack-type piezoelectric element.
