Abstract
The present invention provides an ink jet head comprising a head substrate , a heat-generating resistor and a pair of electrodes , which are attached on the head substrate , and a top plate disposed above the head substrate , the ink jet head being capable of ejecting ink, with which the space between the head substrate and the top plate is filled, through an ink ejection opening by means of heat of the heat-generating resistor, wherein the heat-generating resistor is made of a silicon oxide material selected from the group consisting of (1) a material consisting of Ta SiO (1.30≦x≦1.70 and 1.20≦y≦1.95), (2) a material consisting of Nb SiO (1.4≦x≦1.9 and 1.4≦y≦1.9), (3) a TiC—SiO resistive material, a TiC content in the resistive material being set within a range from 55 to 90 mol %, and (4) a Ta—Ni—SiO (1.2≦x≦2.0) resistive material, a Ta content in the resistive material being set within a range from 48 to 70 atomic %, a Ni content being set within a range from 0.1 to 2.0 atomic %. This ink jet head can record an image with less strain and uneven density at a high speed, and also has a high reliability.
