摘要： A liquid ejection head includes: a substrate which has an energy-generating element that generates energy to be utilized for ejecting a liquid, and a supply orifice for supplying the liquid to the energy-generating element; and an ejection orifice forming member that has a plurality of ejection orifices through which the liquid is ejected, and at least one beam-like projection which projects toward the substrate and extends along an array direction of the ejection orifices at a position corresponding to the supply orifice; wherein a sectional area perpendicular to the array direction of the ejection orifices in the central part of the beam-like projection in the array direction of the ejection orifices is larger than a sectional area in the direction perpendicular to the array direction of the ejection orifices in both ends of the beam-like projection in the array direction.
摘要翻译：液体喷射头包括：基板，其具有产生用于喷射液体的能量的能量产生元件和用于将液体供给到能量产生元件的供给孔口; 以及喷射孔口形成构件，其具有多个通过其喷射液体的喷射孔口，以及至少一个朝向基板突出并沿着喷射孔口的排列方向在对应于供给的位置处延伸的梁状突起孔; 其特征在于，在所述射出孔的排列方向上，所述射束状突起的中央部的与所述射出孔的排列方向垂直的截面积大于与所述射出孔的排列方向垂直的方向的截面积束状投影的两端在阵列方向上。
