摘要：
To provide an ink jet head having a good stability of ejection and a method of manufacturing the ink jet head, a method of manufacturing an ink jet head that includes a cavity and a nozzle connected to the cavity and ejects fluid contained in the cavity from an ejection opening that is an opening provided on a side of the nozzle opposite to the cavity. An inside-nozzle lyophobic film is formed in the vicinity of the ejection opening and on the inside wall of the nozzle, the inside-nozzle lyophobic film providing a large difference between an advancing contact angle and a receding contact angle for the liquid to be ejected.
