PIEZOELECTRIC DEVICE, INKJET PRINT HEAD AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric device, an inkjet print head, and a method of manufacturing the same.

SOLUTION: The piezoelectric device includes piezoelectric ceramic powder containing 90 pts.wt. or more and less than 100 pts.wt. of Pb(Zr, Ti)O3, and more than 0 pts.wt. and 10 pts.wt. or less of glass frit, based on 100 pts.wt. of a piezoelectric substance composition for the piezoelectric device, where the glass frit may contain 10 to 20 pts.wt. of ZnO, based on 100 pts.wt. of glass frit.
