Abstract
Disclosed is a method of manufacturing a liquid ejecting head where first and second members with different sizes which are formed of silicon are laminated with an adhesive agent. The method includes measuring a distance between a reference point which is positionally aligned in the laminating direction with respect to an imaging unit and a surface which extends from the bonding surface of the second member, and imaging the bonding surface by calculating a focal point distance of the imaging unit based on the distance which is measured and a distance between the imaging unit and the reference point.
