Liquid ejecting head manufacturing method, liquid ejecting head, and liquid ejecting apparatus

Abstract

There is provided a liquid ejecting head manufacturing method of manufacturing a second liquid ejecting head by regenerating a first liquid ejecting head that includes a first head chip ejecting a liquid, and a flow path structure having a first selection coupling portion and a second selection coupling portion that are flow path coupling portions to the first head chip, the method including: a replacing step of replacing the first head chip with a second head chip compatible with the first head chip, in which the replacing step includes a first step of releasing an adhesion state where the first selection coupling portion and the first head chip are liquid-tightly coupled, and a second step of liquid-tightly coupling the second selection coupling portion compatible with the first selection coupling portion and the second head chip by an adhesive.
