PROBLEM TO BE SOLVED: To prevent adverse effect on recording quality due to shift between a substrate and a nozzle pitch by virtue of an ambient temperature and heating of a recording head and lowering of adhesion between a nozzle wall and a substrate without changing a material. SOLUTION: The ink jet recording head consists of a top plate 1 having an ejection nozzle 11 for ejecting ink and a groove 12 communicating to the ejection nozzle 11 and the substrate 2 which comprises a heater 21 as an ejection energy generating element provided thereon and is bonded to the top plate 1. The shift between the top plate 1 and substrate 2 due to the temperature change of the recording head is absorbed by elasticity of the nozzle.
