    • A liquid ejection head includes a substrate having an energy-generating element for generating energy to be used for ejecting a liquid and a supply port in the form of a through-hole for supplying the liquid to the energy-generating element, and an orifice plate including an ejection orifice for ejecting the liquid. A plurality of the energy-generating elements is arranged in a first direction. The supply port is formed between the plurality of the energy-generating elements in the first direction, and the supply port is formed so as to be adjacent to the energy-generating element in a second direction orthogonal to the first direction.
    • 液体喷射头包括具有用于产生用于喷射液体的能量的能量产生元件的基板和用于将液体供应到能量产生元件的通孔形式的供给口,以及孔板 包括用于喷射液体的喷射口。 多个能量产生元件沿第一方向布置。 供给口沿着第一方向形成在多个能量产生元件之间,供给口形成为与第一方向正交的第二方向与发电元件相邻。
