PROBLEM TO BE SOLVED: To provide an inkjet head that can reduce a temperature difference of ink in the individual liquid chamber caused by the heat generated by a driving IC chip inserted in the inkjet head.SOLUTION: An inkjet head includes: a driving IC chip 105a; heat dissipation members 201a, 202; and a housing 104, wherein, a nozzle plate 2, a channel plate 101, a diaphragm, an actuator substrate 14, a sub-frame 102, a common liquid chamber formation substrate 103, and a manifold 106 are sequentially accumulated. Through-holes 203a and 203b are formed in the common liquid chamber formation substrate 103 and the manifold 106 toward the housing 104 from the driving IC chip 105a in a neighborhood of the terminal part of the common liquid chamber. The heat dissipation members 201a and 202 that are touched by at least one surface of the driving IC chip 105a is touched by the housing 104 through the through-holes 203a and 203b. |
