摘要： 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.

摘要： A printing head is provided in which a distance between an ejection port face of the printing head and a print medium is reduced to improve an ink ejection accuracy during a printing operation. The printing head of the present invention is a back shooting-type printing head. The heater and an electrode connected thereto are formed at the back face of the substrate. The electrode and an in-support-base wiring for supplying electricity to the heater via the electrode are connected to each other at the back face side of the substrate. The substrate and the support base have therebetween a liquid chamber wall member including therein a space. The substrate, the support base, and the liquid chamber wall member constitute a liquid chamber that communicates with the ejection port and that stores ink supplied to the ejection port.
