PROBLEM TO BE SOLVED: To provide an inkjet recording head capable of reducing a time period of refilling and suppressing an influence of a back flow. SOLUTION: This inkjet recording head comprises a device board having a plurality of ejection energy generating devices for generating a bubble in a liquid by thermal energy provided on an identical face, and a supply path forming device in which a plurality of bubble generating chambers each including the ejection energy generating device and a plurality of supply paths for introducing the liquid to each of the bubble generating chambers are formed on a face opposite to the face having the bubble generating chambers and a plurality of nozzles communicating each of the bubble generating chambers with the external section of the head. The positions of supply path opening faces perpendicular to the device board as flow-in/out holes of the supply paths are alternately deviated in a direction perpendicular to the device board in an identical nozzle array.
