PROBLEM TO BE SOLVED: To provide a liquid jetting device which solves the problem of non-linearity or hysteresis resulting from ferroelectric characteristics of a piezoelectric body in a relationship between a driving voltage and a displacement amount, and the problem that a piezoelectric driving element has to be manufactured at a high temperature, and which attains the improvement in the high precision and the speeding up. SOLUTION: This liquid jetting device comprises a liquid injecting port 5 for injecting a liquid, a liquid storage section 6 for storing the injected liquid, and a liquid jetting port 7 for jetting the stored liquid. The liquid jetting device also has the piezoelectric driving element 1 for pressurizing the liquid in order to jet the liquid being stored in the liquid storage section from the liquid jetting port 7, and a vibrating plate 3 which is vibrated by the piezoelectric driving element. The piezoelectric driving element has a piezoelectric body sheet 20B of non-ferroelectricity for the liquid jetting device. COPYRIGHT: (C)2006,JPO&NCIPI
