PROBLEM TO BE SOLVED: To provide a liquid discharge head with less fluctuation of discharge characteristics by resonance of the liquid discharge head, and provide a recording device using the same.SOLUTION: A liquid discharge head includes: a flow passage member 4 which has a plurality of discharge holes and a plurality of pressurization chambers connected to the plurality of discharge holes respectively; and a piezoelectric actuator substrate 21 which is joined to the flow passage member 4 and has a plurality of displacement elements for respectively pressurizing liquid in the plurality of pressurization chambers. The flow passage member 4 has a flat-plate-shape which is long in one direction. In a plane view of the flow passage member 4, a wide part W which is wide in other direction orthogonal to the one direction, and a narrow part N which is narrower than the wide part W are alternately arranged over the one direction. |
