Abstract
Providing is a liquid discharge head less susceptible to a standing wave occurred in a shared flow path; a liquid discharge device using the liquid discharge head; and a recording apparatus. The liquid discharge head includes a plurality of liquid discharge pores; a plurality of liquid pressing chambers 210 respectively connected to the plurality of liquid discharge pores; a shared flow path 205a being long in one direction and being linked the plurality of liquid pressing chambers 210; a liquid supply path 205c which is connected to both ends of the shared flow path 205a, and has a larger cross-sectional area than the shared flow path 205a; and a plurality of pressing parts for respectively pressing liquid in the plurality of liquid pressing chambers 10. The cross-sectional area of a middle segment of the shared flow path 205a is smaller than the cross-sectional area of that of each of both end segments thereof.
