    • A liquid ejection head including: includes an ejection orifice for ejecting liquid, a pressure chamber communicating with the ejection orifice, a flow path for supplying the liquid to the pressure chamber, and a first heat-generating element and a second heat-generating element for generating energy to be used for ejecting the liquid. The first heat-generating element is arranged in the pressure chamber before the second heat-generating element with respect to a supply direction of the liquid from the flow path to the pressure chamber. A portion between the first heat-generating element and the second heat-generating element is located within a projection of an opening of the ejection orifice, when viewed from a direction in which the liquid is ejected from the ejection orifice.
    • 一种液体喷射头,包括:包括用于喷射液体的喷射孔,与喷射孔连通的压力室,用于将液体供应到压力室的流路,以及第一发热元件和第二发热元件, 产生用于喷射液体的能量。 第一发热元件相对于液体从流路到压力室的供给方向设置在第二发热元件之前的压力室中。 当从喷射口喷射液体的方向观察时,第一发热元件和第二发热元件之间的部分位于喷射孔的开口的突出部内。
