Abstract: Provided is an inkjet print head in which, without causing an increase in print head size, printing elements that can perform ejection at a high frequency are densely arrayed. For this purpose, an ink supplying port and a wiring line, which are common to a predetermined number of printing elements, are prepared, and a substrate on which the ink supplying ports and the wiring lines are alternately arranged at the same pitches as an array pitch of the printing elements is also prepared.

Abstract: A liquid ejection head includes a substrate including a first supply port row in which a plurality of supply ports are arranged, a first energy generating element row in which a plurality of energy generating elements are arranged, a second supply port row in which a plurality of supply ports are arranged, a second energy generating element row in which a plurality of energy generating elements are arranged, a first wiring layer and a second wiring layer for driving the energy generating elements, and a through hole configured to electrically connect the first wiring layer and the second wiring layer. The first energy generating element row, the first supply port row, the second supply port row, and the second energy generating element row are arranged in parallel in this order and the through hole is arranged between the first supply port row and the second supply port row.

Abstract: An ink jet print head is configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. An individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber are symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of the pressure chamber.

Abstract translation: 喷墨打印头被配置为减小墨水喷射方向的倾斜，使得诸如条纹和密度不均匀的不正确打印条件不明显。 单独的电线延伸到普通电线下方。 因此，布置在压力室的相应相对侧的墨水通道下方的电线是对称的。 因此，在设置在压力室的各个相对侧的墨水通道的底部设置有等效的台阶结构。
