PROBLEM TO BE SOLVED: To provide a liquid discharge head which detects a liquid temperature in a common liquid chamber with high accuracy by using a simple structure.SOLUTION: A liquid discharge head includes: multiple nozzles 4 for discharging droplets; individual liquid chambers 6 to which the nozzles 4 respectively lead; fluid resistance parts 7 which respectively supply a liquid to the individual liquid chambers 6; liquid introduction parts 8 respectively leading to the fluid resistance parts 7; and a common liquid chamber 10 which supplies the liquid from a supply port to the individual liquid chambers 6 through the liquid introduction parts 8. A heat conductive member 41 is disposed in an entire region of the common liquid chamber 10 in a nozzle arrangement direction. Both sides of the heat conductive member 41 are open in a direction perpendicular to the nozzle arrangement direction, and a temperature detection element 42 which detects a temperature is provided in the heat conductive member 41. |
