ABSTRACT:
An ink jet head comprises an discharging element having discharging ports to discharge ink, ink passages conductively connected to the foregoing discharging ports, and exothermic elements giving thermal energy to ink distributed in the ink passages, and at least a part of such an element is covered with a silicone resin, the amount of low molecular siloxane content of which is 500 ppm or less. Thus, in a thermal jet recording head, the low molecular siloxane divergence is lowered in its process of hardening or after hardening to enable the reduction of the occurrence frequency of the abnormal ink foaming, contributing to the improvement of the reliability of the thermal jet recording head as well as to the improvement of the yield in its fabrication.
