PROBLEM TO BE SOLVED: To provide an inkjet recording head or the like capable of decreasing deviation of the delivering direction and generation of non-delivering phenomenon caused by piling up of ink generated on an ink delivering face. SOLUTION: The inkjet recording head has a plurality of ink delivering holes 1, ink flow paths 6 respectively communicated with the ink delivering holes 1, and ink delivering energy generating elements 7 arranged in respective ink flow paths 6. A plurality of rows of delivering holes made by arranging a plurality of the ink delivering holes 1 in lines on the ink delivering face on which the ink delivering holes 1 are opened. Channels 2 extending in the lengthwise direction of the rows of the delivering holes are formed between a plurality of the rows of the delivering holes on the ink delivering face, and an acute angle is formed by the wall face of the channel 2 and the ink delivering face.
