<p>The objective of the present invention is to provide an inkjet head that can achieve a higher density of nozzles and can prevent ink discharge problems. The inkjet head is characterized by being provided with: a head substrate having a plurality of pressure chambers, a plurality of piezoelectric elements, a plurality of drive electrodes, and a plurality of ink introduction ports; a wiring substrate having a plurality of ink supply ports and wiring that supplies power to the piezoelectric elements; and a spacer layer having a resin section sandwiched between the head substrate and the wiring substrate in a manner so as to cause both substrates to be at a predetermined spacing, and a void section where the resin section is not present. The inkjet head is further characterized by: the head substrate and the wiring substrate being joined, by means of the resin section of the spacer layer, across a duct hole disposing region, which contains all of the sites at which duct holes are disposed between the head substrate and the wiring substrate, and a duct hole non-disposing region, which is provided in a manner so as to encircle the duct hole disposing region and at which duct holes are not disposed; and the resin section at the duct hole non-disposing region being formed by means of a plurality of columnar bodies sandwiched between the head substrate and the wiring substrate.</p> |
