<p>PURPOSE:To simplify the constitution of a thin film heating resistor, and improve the thermal efficiency and ink discharge frequency drastically for a recording device which makes ink liquid drops fly to a recording medium by pulse heating. CONSTITUTION:A heating resistor which is provided in the vicinity of an orifice is constituted of a Cr-Si-SiO or Ta-Si-SiO alloy thin film resistor 3/Ni thin film conductor 4. Also, at a side end part of an ink reservoir 9 of an ink passage 8, a space which extends to the ink reservoir side is formed, and a heating resistor is provided in the space, or a separate heating resistor is provided.</p> |
