Abstract
Provided is an inkjet print head capable of favorably cleaning an ejection port surface and also of improving landing accuracy of ejected ink onto a print medium. For that purpose, a conductive layer formed of a conductive material is formed on a support substrate, flattening processing is executed, and a liquid ejection substrate is mounted on the support substrate with good positional accuracy without protrusion of a sealant for protecting an electric connection portion of the liquid ejection substrate from the ejection port surface.
