LIQUID JET HEAD AND LIQUID JET APPARATUS

摘要

A liquid jet head includes a side wall installed between channels, and in which two piezoelectric materials having mutually different polarization directions are laminated in a height direction, interposing a polarization boundary, an upper member fixed to an upper end of the side wall and installed on an upper portion of the channel, a lower member fixed to a lower end of the side wall and installed on a lower portion of the channel, and an electrode installed on a wall surface of the side wall, wherein the polarization boundary is positioned above ½ the height of the side wall, and the electrode is installed from an upper end of the wall surface, to a vicinity of the polarization boundary, or below the polarization boundary and above a lower end of the wall surface.
