PROBLEM TO BE SOLVED: To reduce as much as possible a position shift between an ink pressurizing chamber having a heating resistor and an ink ejection nozzle corresponding to the ink pressurizing chamber. SOLUTION: A substrate member 5 forming a side wall of the ink pressurizing chamber 7 and one end face and having a heating resistor 6 and a nozzle forming member 2 forming the other end face of the ink pressurizing chamber and having an ink ejection nozzle 3 corresponding to the ink pressurizing chamber are stuck with each other at a high temperature to form a print head 1. When sticking them, the positions of the substrate member and the nozzle forming member are aligned with each other at a center of the substrate member.
