PROBLEM TO BE SOLVED: To provide an inkjet head that can approximately uniformize an ink temperature by dissipating heat generated from a driving IC chip inserted into an inkjet head to ink in a common liquid chamber.SOLUTION: An inkjet head includes: a nozzle plate 2; an individual liquid chamber forming substrate 101; an actuator substrate 14 having a pressure generating element, and a driving IC chip 105; a first heat dissipating member 202 that transfers heat from the driving IC chip to liquid; a second heat dissipating member 201 that transfers heat from the driving IC chip to the first heat dissipating member; a common liquid chamber forming substrate 103 in which a common liquid chamber for supplying the liquid to the common liquid chamber is formed; and a manifold in which a supply hole for supplying the liquid to the common liquid chamber is formed. The first heat dissipating member is disposed so that at least some of the heat dissipating member contacts the liquid supplied to the common liquid chamber along a center axis of the supply hole. |
