PURPOSE:To obtain the printing head of reliable, highly productive and low cost by a method wherein metallic plates are laminated between piezoelectric elements and vibrating plates and a voltage is impressed to the piezoelectric elements through these metallic plates. CONSTITUTION:The metallic plate 8, obtained by etching or pressing and having the thickness of 30-80mum, the vibrating plate 3, coated with an adhesive agent 4, and the piezoelectric element 1 having a metallizing film 2 on the surface thereof, are laminated into a direction shown by arrow signs and pressed to adhere them. The piezoelectric element 1 having the metallizing film 2 resistive against environmental changes such as a temperature change and the like may be bonded to the vibrating plate 3 while a conductance to the piezoelectric element 1 having the metallizing film 2 on the surface thereof may be obtained by impressing the voltage through these metallic plates 8. |
