Abstract | To suppress deviation of a direction of discharging a liquid from a direction vertical to a discharge surface.SOLUTION: A liquid discharge head has a first drive element, a first pressure chamber which is partitioned by a pressure chamber substrate and imparts a pressure to a liquid by drive of the first drive element, and a first nozzle which is formed on a nozzle substrate, communicates with the first pressure chamber and discharges a liquid, wherein the nozzle substrate has a first surface and a second surface closer to the pressure chamber substrate than the first surface, the first nozzle includes a first upstream nozzle part including a first supply opening opened to the second surface and a first bottom surface facing the first supply opening, and a first downstream nozzle part including a first discharge opening opened to the first surface and a first connection part opened to the first bottom surface, when be viewed in a thickness direction of the nozzle substrate, a cross-sectional area of the first upstream nozzle part is larger than a cross-sectional area of the first downstream nozzle part, and when be viewed in the thickness direction, the center of gravity of the first connection part is positioned between the center of gravity of the first discharge opening and the center of gravity of the first bottom surface.SELECTED DRAWING: Figure 4
【課題】液体が吐出する方向を吐出面に垂直な方向からずれることを抑制すること。【解決手段】液体吐出ヘッドは、第1駆動素子と、圧力室基板に区画され、第1駆動素子の駆動により液体に圧力を付与する第1圧力室と、ノズル基板に形成され、第1圧力室と連通し、液体を吐出する第1ノズルと、を備え、ノズル基板は、第1面と、第1面よりも圧力室基板に近い第2面と、を有し、第1ノズルは、第2面に開口した第1供給開口と、第1供給開口に対向する第1底面と、を含む第1上流ノズル部分と、第1面に開口した第1吐出開口と、第1底面に開口した第1接続部とを含む第1下流ノズル部分と、を含み、ノズル基板の厚さ方向にみたとき、第1上流ノズル部分の断面積は、第1下流ノズル部分の断面積よりも大きく、厚さ方向にみたとき、第1接続部の重心は、第1吐出開口の重心と第1底面の重心との間に位置する。【選択図】図4 |
