Abstract:
A manufacturing method for a print head, in which a substrate member, which forms side surfaces and one end surface of ink-pressurizing cells and which is provided with heating elements, is laminated at a high temperature to a nozzle-formed member, which forms the other end surface of the ink-pressurizing cells and in which ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed, the manufacturing method for the print head comprising the steps of:laminating the nozzle-formed member to a head frame, which has the same coefficient of linear expansion as the substrate member, at a temperature T1, which is higher than room temperature; and laminating the substrate member to the nozzle-formed member at a temperature T2, which is higher than room temperature, wherein the temperature T1 is higher than the temperature T2.
