INKJET HEAD

PROBLEM TO BE SOLVED: To provide a high-performance inkjet head that can record a good image and can cope with high-speed recording. SOLUTION: The inkjet head according to the present invention is constituted such that an ink 7 is jetted by thermal energy. The inkjet head has a head substrate 1 constituted by including a base plate 2, a large number of heating resistors 3 arranged in a main scanning direction on the upper face of the base plate 2, and a pair of power supplying wires 4 electrically connected to the large number of heating resistors 3 respectively and in which pads 4a for pulse trimming are formed, a top plate 5 with a width narrower than that of the base plate 2 in a sub scanning direction of crossing the main scanning direction, and spacers interposed between the head substrate 1 and the top plate 5 and forming a gap for filling the ink 7, the pads 4a for pulse trimming are located outside of the arranging area of the top plate 5 and outside of the gap.
