ABSTRACT:
A liquid jet recording head comprises a substrate comprising a support, a resistive heater layer, electrodes electrically connected with the resistive heater layer, a portion of the resistive heater layer located between the electrodes being an electrothermal transducer, and an upper layer comprising a first protective layer comprising an inorganic insulating material, a second protective layer comprising an inorganic material, and a third protective layer comprising an organic material, wherein and the second protective layer and the third protective layer overlap each other in the vicinity of a portion where heat is generated by the electrothermal transducer and the overlapping width of the second protective layer and the third protective layer ranges from 10 .mu.m to 500 .mu.m. In another embodiment, the second protective layer extends along plural liquid flow paths for substantially less than the length thereof in a continuous strip that covers adjacent transducers.
