Abstract
An ink jet head is provided which includes an electrothermal converting body having a heat generating resistor which generates, upon energization, heat energy to be directly applied to ink on a heat acting face to discharge the ink. The ink jet head is characterized in that the heat generating resistor is formed from a non-single crystalline substance substantially composed of Ir and Ta and containing the Ir and Ta at the following respective composition rates: 35 atom percent .ltoreq.Ir.ltoreq.77 atom percent, and 23 atom percent .ltoreq.Ta.ltoreq.65 atom percent.
