The inkjet printer head includes heating elements and ejection nozzles. Each of the heating elements has a heating resistor which is energized by application of an electric current so that a part of ink which is located in proximity to the heating resistor is boiled to form a bubble. The expansion of the formed bubble causes the ink to be ejected as a droplet through each of the ejection nozzles. Each of said heating elements has no protective film disposed between the heating resistor and the ink in which the bubble is to be formed. A thickness of said heating resistor is in a range of from 2 μm to 5 μm.
