Abstract

PURPOSE: To permit the thermal shock jet of ink with good efficiency from nozzle as well as lengthen the life of resistor elements by a method in which plural resistor elements are set separately from each other and also from the position facing the center of a nozzle for one nozzle and they are connected in series with one another.
CONSTITUTION: Heating resistors 8 and conductor layers 10 are provided through a heat insulator layer 4 on a base plate 2, and an orifice 20 is formed through a passivation layer 12 and barrier elements 14 and 16 on an orifice plate 18. In a thermal shock ink jet head having such the orifice plate 18, plural resistor layers 8' and 8" are set separately from each other and also from the position facing the central part of the orifice 20 and connected in series with conductor layers 10, 10' and 10". Damage to the heating resistor elements by cavitation phenomenon to be caused in the position facing the central part of the orifice 20 can thus be completely prevented.
