ABSTRACT:
A method of preparing an ink jet head comprises a support, an electrothermal transducer formed on said support and having a heat-generating resistor and a pair of electrodes connected electrically to said heat-generating resistor, and a liquid path formed on said support corresponding to the heat-generating portion of said electrothermal transducer formed between said pair of electrodes, and communicating with a discharge opening for discharging liquid, which comprises the step of dry etching to pattern the material for said heat-generating resistor provided on said support in the form of a layer.
