<P>PROBLEM TO BE SOLVED: To provide an inkjet head which prevents a variation in ink viscosity caused by the generation of heat. <P>SOLUTION: The inkjet head in which an element for the discharge of ink generates heat accompanied by operation includes: a nozzle plate 12 having three or more nozzle trains which are laterally aligned; and a heat radiation member 14 provided in the nozzle plate 12 for radiating heat from the three or more nozzle trains whose temperatures are increased accompanied by the generation of heat. The heat radiation member 14 differs in heat dissipation rate in the direction of the lateral alignment so that the temperatures of the three or more nozzle trains may be uniform. <P>COPYRIGHT: (C)2013,JPO&INPIT |
