<p>PURPOSE: To eliminate damage during handling or processing and to increase the strength of a processed part to enhance reliability by integrally providing a recording material flying structure on a recording material supply structure part. CONSTITUTION: Heat of 50-500 deg.C is generated in a heating element 75 by the supply of a current and a liquefied dye 22 is heated by this heat to be evaporated. Since a spacer 82 composed of quartz glass is integrally provided under an insulating plate 73, the spacer 82 acts as a heat insulating material and the heat due to the heating element 75 is hardly dissipated. The supply passage 84 of the liquefied dye 22 is formed to the spacer 82 and opened to the bottom surface of a dye housing part 87 as a dye introducing port 84'. Since an insulating plate 73 is integrated on the spacer 82, this integrated structure becomes thick to be increased in mechanical strength. Therefore, mechanical strength at the time of the processing of the dye housing part 87, a small pillar element 80 and the dye passage 84 becomes sufficient and a crack or destruction is not generated and handling properties, processability or reliability can be enhanced.</p> |
