LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE APPARATUS

The invention provides a liquid discharge head and a liquid discharge device which can improve the cooling efficiency and stabilize the temperature even if the amount of heat generated by a drive control IC increases. The liquid discharge head according to an embodiment includes a head body having a plurality of ejection holes; a supply part that supplies liquid to the head body; a cooling unit arranged at a certain distance from the head body, supplied with liquid passing through the head body and forming a flow path, in which cooling liquid flows; a first substrate arranged between the headbody and the cooling unit and provided with a control element; a second substrate having one end side connected to the head body and the other end side connected to the first substrate, wherein the second substrate carries a drive control element for the head body; and a heat conduction member having one end side connected to the inside of the cooling unit and the other end side thermally connected to the drive control el
