ABSTRACT:
An ink-jet recording head whose nozzles and ink flow channels can readily be formed and thus mass produced and which uses inexpensive glass and plastic plates. A combination of an oscillating plate 2 and an intermediate film 3, and that of an intermediate nozzle film 5 and a terminal nozzle plate 6 are each joined together by bonding adhesives, whereas a combination of an intermediate film 3 and a cavity plate 4, and that of the cavity plate 4 and the intermediate nozzle film 5 are each joined together by thermal fusion bonding. As the melt temperatures 190.degree. C. of an intermediate film 3 of polysulfone and the intermediate nozzle film 5 are lower than the thermal deformation temperature 200.degree. C. of the cavity plate 4 of polyetherimide, the pressurizing chambers 4d and flow channels 4c of the cavity plate 4 are made free from thermal deformation. Moreover, the inner face of a through-hole comprising the entry port 4a, reservoir 4b, flow channel 4c and pressurizing chamber 4d of the cavity plate 4, and the inner face of the intermediate nozzle 5a of the intermediate nozzle film 5 are so treated that they are made hydrophilic through an ozonizing process, whereas the inner and open faces of a terminal nozzle 6a are so treated that they are made water-repellent.
