Abstract:
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, whereinthe heat-generating resistor is made of a silicon oxide material selected from the group consisting of (1) a material consisting of TaxSiOy (provided that x and y meet the expressions: 1.30&lE;x&lE;1.70 and 1.20&lE;y&lE;1.95), (2) a material consisting of NbxSiOy (provided that x and y meet the expressions: 1.4&lE;x&lE;1.9 and 1.4&lE;y&lE;1.9), (3) a TiCâ€”SiO2 resistive material, a TiC content in the resistive material being set within a range from 55 to 90 mol %, and (4) a Taâ€”Niâ€”SiOx (provided that x meets the expression: 1.2&lE;x&lE;2.0) resistive material, a tantalum (Ta) content in the resistive material being set within a range from 48 to 70 atomic %, a nickel (Ni) content being set within a range from 0.1 to 2.0 atomic %.
