(EN) 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 characterize4d by being 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 inksupply opening formation surface 600 of the head chip 2 and retaining the ink chamber 3. 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.
(ZH) 本发明的要解决的问题在于提供一种能以简易的结构高精度地分离墨室的喷墨头等。本发明的喷墨头(1)的特征在于，包括：喷墨头芯(2)，所述喷墨头芯(2)包括多个喷嘴(11)与多个喷嘴(11)分别连通的多个压力室(311)、和通过使多个压力室(311)的内部发生压力变化而射出墨的压电元件(42)；墨室(3)，所述墨室(3)贮存墨；保持部(90)，所述保持部(90)接合于喷墨头芯(2)的墨供给孔形成面(600)，保持墨室(3)，保持部(90)包括保持墨室的外周壁(3a)的外周壁保持部(90a)和保持墨室(3)的分离壁(3b)的分离壁保持部(90b)，墨室(3)被分离壁(3b)和分离壁保持部(90b)分离成多个。
