    • A liquid discharging head includes a head chip including a plurality of energy generating elements configured to discharge liquid and liquid chambers provided around the corresponding energy generating elements, and a common passage member configured to define a common passage communicating with all the liquid chambers in the head chip. the liquid is discharged from the liquid chambers by driving the energy generating elements so as to apply a discharging force to the liquid. The common passage member includes an inlet through which the liquid is supplied to the common passage, and an outlet through which the liquid is ejected from the common passage. The common passage includes a ceiling surface having a groove extending from the inlet toward the outlet.
    • 液体排放头包括头部芯片,其包括多个能量产生元件,所述多个能量产生元件被配置为排出设置在相应的能量产生元件周围的液体和液体室;以及公共通道构件,其构造成限定与头部中的所有液体室连通的公共通道 芯片。 通过驱动能量产生元件将液体从液体室排出,以向液体施加排出力。 公共通道构件包括入口,液体通过该入口供应到公共通道,以及出口,液体通过该出口从共同通道喷出。 公共通道包括具有从入口朝向出口延伸的凹槽的顶面。
