PROBLEM TO BE SOLVED: To provide an inkjet head which can suppress power consumption, improve the performance of a driving part, and stably discharge ink even when the ink has a high viscosity. SOLUTION: The inkjet head 10 has a head body 11 with a recess 11a for storing the ink and an orifice 11b for discharging the ink, a liquid chamber 12, a diaphragm 13, a magnetic force generating part 14, a ball screw 15, a plurality of magnetic force generating bodies 16, a guide rail 17, an ink reservoir 18, and the like. The diaphragm 13 consists of a film layer with a flexibility to be deformable so that the ink of the liquid chamber 12 can be discharged and filled, and a magnetic layer with a magnetism formed to a face of the opposite side to the liquid chamber 12 of the film layer. The magnetic force generating part 14 is arranged via a space of a predetermined interval from the diaphragm 13. The ball screw 15 can freely change the interval between the diaphragm 13 and the magnetic force generating part 14. COPYRIGHT: (C)2005,JPO&NCIPI
