PROBLEM TO BE SOLVED: To provide a liquid discharge head for preventing heat generated by an energy generating element from being transferred to one portion on a substrate in a converging manner.SOLUTION: A liquid discharge head with at least one energy generating element that generates heat used for discharging a liquid, comprises: an insulation layer provided in contact with a substrate and supporting the energy generating element; at least one heat transfer layer composed of a material of heat conductivity higher than that of the material of the insulation layer, and provided in the insulation layer between the energy generating element and the substrate; and a heat transfer member that thermally connects the at least one heat transfer layer and the substrate. The heat transfer member is connected to an area other than the area of the heat transfer layer, which is located right below the position sandwiched between the energy generating element and the substrate.SELECTED DRAWING: Figure 5 【課題】エネルギー発生素子で生成された熱を基板上の一部分に集中して伝導させないようにするための液体吐出ヘッドを提供する。【解決手段】液体を吐出させるために利用される熱を生成する少なくとも１つのエネルギー発生素子を備えた液体吐出ヘッドであって、基板に接するように設けられ、前記エネルギー発生素子を支持する絶縁層と、前記絶縁層の材質よりも高い熱伝導率の材質で構成され、前記エネルギー発生素子と前記基板との間であって前記絶縁層中に設けられる少なくとも１つの伝熱層と、前記少なくとも１つの伝熱層と前記基板との間を熱的に接続する伝熱部材と、を備え、前記伝熱部材は、前記伝熱層のうち前記エネルギー発生素子と前記基板とで挟まれた位置にある直下領域以外の領域に接続される。【選択図】図５
