Abstract (en)
[origin: WO0069635A1] Forming a heating resistor which emits heat by electric current applied thereto, with non-metallic materials comprising at least tantalum (Ta), silicon (Si), oxygen (O), and nitrogen (N). In a case where such heating resistor has mole ratio Si/Ta of 0.35<Si/Ta<0.80, oxygen mol% of 25 mol% to 45 mol%, and nitrogen mol% of 5 mol% to 25 mol%, the heating resistor shows resistivity equal to or greater than 4 m OMEGA cm, peak angle 2 theta of X-ray diffraction strength is equal to or smaller than 37.5 degrees, and has resistance over 100,000,000 pulses. The heating resistor having the above characteristics is suitable for a print head of a thermal ink-jet printer. Further, the heating resistor shows stable but high resistivity, after the heating resistor is annealed.
