Abstract

In addition, the print head includes substrate members which form side surfaces and one end surface of the ink-pressurizing cells, and which are provided with the heating elements; a nozzle-formed member which forms the other end surface of the ink-pressurizing cells, and in which the ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed; and a head frame which supports the nozzle-formed member.
