PROBLEM TO BE SOLVED: To efficiently conduct heat between an inkjet head body and a liquid flowing inside a passage in the case where temperatures of the inkjet head body and ink are maintained at an appropriate temperature by flowing the temperature-adjusted liquid in the passage formed at a base. SOLUTION: There are set the base 3, the inkjet head body 4 bonded and fixed to the base 3 with a plurality of nozzles formed for discharging ink droplets, and the passage 19 formed at the base 3 for flowing the temperature-adjusted liquid. The base 3 has the side where the inkjet head body 4 is bonded and fixed formed of a high heat conductivity material, and the opposite side formed of a material of a lower heat conductivity than that of the high heat conductivity material. The heat conduction between the liquid flowing in the passage 19 and the inkjet head body 4 is efficiently carried out when the temperature-adjusted liquid flows in the passage 19.
