To provide a liquid discharge head which can inhibit temperature rise of a liquid, and to provide a liquid discharge device.SOLUTION: A liquid discharge head according to an embodiment comprises a liquid discharge part, an inflow pipe part, an outflow pipe part, and a cooling device. The liquid discharge part includes: a first common chamber; an actuator forming pressure chambers connected to the first common chamber; and a second common chamber connected to the pressure chambers. The inflow pipe part supplies a liquid to the first common chamber. The outflow pipe part discharges the liquid from the second common chamber. The cooling device includes: a cooling plate thermally connected to the outflow pipe part; and a cooling passage which is provided at the cooling plate and through which a coolant passes.SELECTED DRAWING: Figure 4 【課題】液体の温度上昇を抑制できる液体吐出ヘッド及び液体吐出装置を提供すること。【解決手段】一実施形態に係る液体吐出ヘッドは、液体吐出部と、流入管部と、流出管部と、冷却装置と、を備える。液体吐出部は、第１共通室、前記第１共通室に接続された複数の圧力室を構成するアクチュエータ、及び、前記複数の圧力室に接続された第２共通室を含む。流入管部は、前記第１共通室に液体を供給する。流出管部は、前記第２共通室から前記液体を排出する。冷却装置は、前記流出管部に熱的に接続する冷却板、及び、前記冷却板に設けられ、冷却水が通過する冷却流路を含む。【選択図】 図４
