ABSTRACT:
The present invention is related to an ink jet head comprising a substrate having a support, an intermediate layer provided on said support and a lower layer provided on said intermediate layer, and a heat energy generating member which generates heat energy to be utilized for discharging ink provided on said substrate. The ink jet head is characterized in that ink channels communicated to discharge openings for discharging ink are formed corresponding to the heat generating portions of said heat energy generating member on said heat generating substrate, and the thermal conductivity of said intermediate layer is selected higher than that of said support and higher than that of said lower layer.
