Patent ID: 6918180

Claim:
A method of manufacturing an ink jet head, comprising the steps of: providing an actuator unit formed with a plurality of actuators extending in the same direction from abase portion to be in parallel with one another, each of said plurality of actuators being made of a plurality of piezoelectric elements extendable in a longitudinal direction causing tip ends of said plurality of actuators to move away from the base portion when an electrical signal is applied to the each of said plurality of actuators; providing a diaphragm; providing an ink channel unit formed with a plurality of ink channels corresponding to respective ones of said plurality of actuators individually; dipping the tip ends of said plurality of actuators into an adhesive pond so that an adhesive agent clings to the tip ends of said plurality of actuators while maintaining a state in which an imaginary first line that connects the tip ends of said plurality of actuators is in parallel with an imaginary second line that connects borders between immersed and non-immersed portions of said plurality of actuators; adhering said actuator unit onto one surface of said diaphragm while abutting the tip ends of said plurality of actuators against the one surface of said diaphragm; and attaching said ink channel unit to another surface of said diaphragm so that said plurality of ink channels are positioned in confronting relation with said respective ones of said plurality of actuators individually.
