The purpose of the present invention is to provide an inkjet head, and the like, for which it is possible to separate an ink chamber in a highly accurate manner by means of a simple configuration. This inkjet head 1 is equipped with: a head chip 2 having a plurality of nozzles 11, a plurality of pressure chambers 311 that respectively communicate with the plurality of nozzles 11, and piezoelectric elements 42 that cause pressure changes inside the plurality of pressure chambers 311 so as to eject ink; an ink chamber 3 for storing ink; and a retainer 90 joined to an ink supply opening formation surface 600 of the head chip 2 and retaining the ink chamber 3. The inkjet head is characterized in that: the retainer 90 has an outer peripheral wall retaining part 90a for retaining the outer peripheral wall 3a of the ink chamber 3 and a dividing wall retaining part 90b for retaining a dividing wall 3b of the ink chamber 3; and the ink chamber 3 is divided into multiple compartments by the dividing wall 3b and the dividing wall retaining part 90b. |
