Abstract

PROBLEM TO BE SOLVED: To obtain an ink-jet head inexpensibly by uniformizing a plurality of characteristics among a plurality of channels to improve productivity by a method wherein dimensions of the channels are ensured by bonding a partition of an ink chamber without using a bonding means such as an adhesive or the like.
SOLUTION: Ink is supplied to a common ink chamber 10 provided to a holding plate 4 from an ink supply tank, and the ink passes through a channel 9 of a plate 5 and a channel plate 28 by a water head difference between the ink and a head and a capillary phenomenon to be filled into a pressurized chamber 11 constituted of a diaphragm 6, a chamber palate 7, and an orifice plate 12. The diaphragm 6 is connected to an electrostrictive element 2 fitted to a base plate 1 held with a spacer 19 via a foot 3. By applying an electronic signal to the electrostrictive element 2 with a drive circuit, a mechanical displacement is generated in the electrostrictive element 2 to deform the diaphragm 6 via the foot 3 being rigid.
