ABSTRACT:
A method for connecting a nozzle tube of an ink jet nozzle of an ink jet printer with a piezoelectric element utilizing a bonding agent, which comprises steps of applying a coating of a material having a relatively low adhesive property to the bonding agent on at least a portion of the piezoelectric element being disposed adjacent to the nozzle tube, and securing the piezoelectric element to the nozzle tube with the bonding agent being applied between the coating and the nozzle tube. The degradation of the characteristics of the piezoelectric element due to the difference in the coefficient of thermal expansion of the piezoelectric element and the bonding agent can be avoided.
