Abstract
An ink jet print head is provided which allows an ejection opening-formed surface to be cleaned well and can improve a precision with which ejected ink lands on a print medium. For this purpose, conductive layers of a conductive material are formed on the support substrate and planarized. The liquid ejection substrates are mounted on the support substrate with high precision, without a sealing agent, that protects electrical connecting portions on the liquid ejection substrates, protruding from the ejection opening-formed surface.
