<P>PROBLEM TO BE SOLVED: To provide a liquid discharge head preventing decline in recording image quality caused by a flow passage structure and a recording device using the liquid discharge head. <P>SOLUTION: The liquid discharge head includes: a flow passage member 4 having liquid pressurization chamber groups in which a plurality of liquid pressurization chambers 10 connected to a plurality of liquid discharge holes 8, respectively are arranged to form a matrix shape and opened on one face; and a plurality of displacement elements 50 stacked on one face of the flow passage member 4 to cover the openings of the liquid pressurization chambers 10. When the same voltage is applied to the plurality of displacement elements 50, displacement of the displacement elements 50 stacked on the outer peripheral liquid pressurization chambers located on the outermost side of the liquid pressurization chamber groups out of the liquid pressurization chambers 10 is set smaller than that of the displacement elements 50 stacked on the inner liquid pressurization chambers other than the outer peripheral liquid pressurization chambers out of the liquid pressurization chambers 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
