Abstract
According to the present invention, there are provided a stack-type piezoelectric element constructed of a stacked body comprising plural layers of sintered piezoelectric ceramic material and electrodes which lie between the respective layers of the piezoelectric ceramic material, wherein said electrodes 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.
