LAMINATED HEAD FOR INK JET RECORDING, PRODUCTION METHOD THEREOF, AND PRINTER EQUIPPED WITH THE RECORDING HEAD

摘要

A laminated head for ink jet recording, having high bonding strength between a vibrating plate and a piezoelectric vibrator and capable of being driven by a low voltage. This recording head comprises a lower electrode disposed in a region on the vibrating plate corresponding to at least a pressure generation chamber, a piezoelectric vibrator formed by a hydrothermal method and laminated on the lower electrode, and an upper electrode laminated on the piezoelectric vibrator, wherein the film thickness of the piezoelectric vibrator is from 1 to 10 mu m. This recording head is used for an apparatus, such as a printer.
