PROBLEM TO BE SOLVED: To suppress temperature rise of a head because of speed-up of recording and densification for reducing density irregularities of an image caused by a temperature difference in a delivering opening array. SOLUTION: The inkjet recording head makes a thermal resistance in a direction to separate from a recording element substrate to a supporting part at the supporting part between the recording element substrate 21 and a supporting plate 10 different between a central region in the delivering opening arrays 51 and 52 direction and an end region.
