PROBLEM TO BE SOLVED: To provide an inkjet recording head which is easy to manufacture, has a high resolution and a low power consumption, and to provide an inkjet recording apparatus. SOLUTION: A belt-shaped resistor 12 is set on a substrate 10 to continuously cover nozzles 20 arranged in an arrow direction. Ink is evaporated by heat generated by heating regions 11 segmented by common electrodes 16 and signal electrodes 14. Ink droplets are discharged from the nozzles 20 by a pressure of generated bubbles. The resistor 12 has the common electrodes 16 at both ends in an arrangement direction (arrow direction) of the nozzles 20 in a pressure chamber 26. The signal electrode 14 is set between the common electrodes 16. In the drawing, for example, in the case where a pitch of the nozzles 20 is 600 dpi and 1200 dpi is realized by arranging shifting the nozzles 20 of two arrays by a half wavelength, although it is conventionally necessary to draw by a pitch of 600 dpi for the heating element 12 as well, the belt-shaped heating element 12 here covers the nozzles 20 of the whole one array, and therefore pattern drawing of the heating element 12 can be made greatly simple.
