ABSTRACT:
A liquid jet head comprises an electrothermal transducer having a heat-generating resistor and a pair of electrodes connected electrically to the heat-generating resistor; a base plate for supporting the electrothermal transducer; a protective layer formed on the electrothermal transducer using an amorphous alloy containing at least one selected from the group consisting of Ti, Zr, Hf, Nb, Ta and W as well as Fe, Ni and Cr; and a liquid path formed on the base plate corresponding to the heat generating portion of the electrothermal transducer formed between the pair of electrodes, and communicated to a discharge opening for discharging liquid.
