摘要 |
An ink jet head is furnished with an electrothermal transducer which has a heat-generating resistor (1). (1), when energised, generates thermal energy, which is utilised for direct heating of an ink on a thermal action plane and thus for jetting the ink. The heat-generating resistor (1) is made of a material contg. Ir, Ta and Al. The component material of (1) is a non-monocrystalline, polycrystalline or amorphous substance, or a mixt. of these. It contains O,C,N,Si,B,Na,Cl or Fe as impurities. (1) has a structure consisting of a laminated plurality of layers. The electrothermal transducer is furnished with a pair of electrodes to conduct electricity to (1) when it is in contact with (1). The thermal action plane comprises (1) alone or (1) and a protective layer formed on it. The protective layer comprises a Ta layer forming the thermal action plane, (1), and an Si insulating layer existing between (1) and the Ta layer. (1) is 300 Angstroms - 1 micron thick (pref. 1000-5000 Angstrom). An ink jet device is equipped with the ink jet head. |
