MANUFACTURING METHOD OF ASSEMBLY, MANUFACTURING METHOD OF LIQUID DISCHARGE HEAD, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an assembly for manufacturing the assembly excellent in reliability, a liquid discharge head excellent in reliability, its manufacturing method and a liquid discharge device loaded with the liquid discharge head. SOLUTION: The positional alignment between members is performed so that the flow direction (in the direction shown by an arrow A) of a resin at the time of injection molding in a case 30 coincides with the flow direction (in the direction shown by an arrow B) at the time of injection molding in a liquid introducing member 40 to join both members. The positional alignment is performed by aligning the mark 35 formed to the guide part 31 of the case 30 with the mark 45 formed on the flange part 43 of the liquid introducing member 40.
