PROBLEM TO BE SOLVED: To provide an inkjet recording head in which variation of temperature distribution of a recording element substrate is more suppressed.SOLUTION: The inkjet recording head 1 includes: a plurality of energy generating elements 14 arranged along a straight line to apply discharge energy to a liquid; a plurality of nozzles 9 to discharge the liquid arranged in a row corresponding to each of a plurality of the energy generating elements 14; a recording element substrate 2 having a single liquid supply port 15 communicating to a plurality of the nozzle; and a soaking member 3, which supports a recording element substrate 2, to make the temperature distribution in a direction of a nozzle row, in which a plurality of the nozzles 9 are arranged, uniform, and the soaking member 3 is penetrated by a channel introducing the liquid to the single liquid supply port 15. The inkjet recording head 1 further includes a heat insulation layer 19 disposed on a wall surface of the channel penetrating the soaking member 3. |
