Abstract
An inkjet recording head includes a recording-element substrate having arranged therein multiple sets of nozzles that discharge ink, energy-generating elements that generate energy used for discharging the ink, and supply ports that supply the ink to the nozzles; and a sealant disposed around the recording-element substrate. The supply ports include a first supply port disposed near a first edge of the recording-element substrate and a second supply port disposed near a second edge of the recording-element substrate, the second edge being opposite to the first edge as viewed in the arrangement direction of the multiple sets. As viewed in the arrangement direction, a distance between the second edge and the second supply port is shorter than a distance between the first edge and the first supply port, and a volume of the sealant near the second edge is smaller than a volume of the sealant near the first edge.
