Abstract: An ink jet head includes a piezoelectric element that is driven in a d33 mode, a pressure generation chamber in which a pressure is generated by the piezoelectric element, and an individual ink supply flow passage that through which the ink is supplied to the pressure generation chamber. The ink jet head includes an individual ink discharge flow passage that through which the ink is discharged from the pressure generation chamber, and a nozzle that ejects the ink from the pressure generation chamber. In a cross-sectional view in a direction orthogonal to an arrangement direction of the nozzle, inner diameters of the pressure generation chamber, the individual ink supply flow passage, and the individual ink discharge flow passage are shorter on a part close to the nozzle than a part close to the piezoelectric element side. Accordingly, an ink jet head capable of ejecting high-viscosity ink can be provided.
