Abstract

The present invention relates to a liquid ejecting head, a liquid ejecting unit, and a liquid ejecting apparatus that efficiently perform monitoring of an adhesive application state and alignment. Theadhesive bonding device comprises a first member (101) and a second member (102) bonded to the first member (101) with an adhesive (103), wherein the first member (101) is provided with a through hole mark (111) as a position alignment mark, and the second member (102) is provided with a first mark (121) and a second mark (122) as position alignment marks, wherein the first mark (121) is a position alignment mark provided with the adhesive (103) in the vicinity of a bonding region (104), and the second mark (122) is a position alignment mark provided with no adhesive (103) in the vicinity ofa region outside the bonding region (104).

Description

technical field [0001] The present invention relates to a liquid spray head, a liquid spray unit and a liquid spray device. Background technique [0002] The liquid discharge head is provided with an alignment mark (alignment mark: Alignment Mark) when bonding a plurality of discharge head constituent members with an adhesive. [0003] Then, for example, two kinds of adhesives are applied to at least one of the first member and the second member to be bonded to each other, and the members are held by the first holding mechanism and the second holding mechanism to face each other, so that each member After contacting each other, pressurize with a weak pressure, contact and press the other part with respect to one part as a reference, keep the posture in the state where the parts are in close contact with each other, and press the The alignment marks provided on each part are used to perform the relative position alignment of each part. After the position is aligned, once the...
