Abstract
A method for producing a liquid discharging head includes an element substrate provided with a discharge opening for discharging a liquid and a supporting member that supports the element substrate, the element substrate having a first surface and a second surface opposite to the first surface, the supporting member having a height reference surface and an element-substrate bonding surface to which the first surface is bonded with an adhesive. The method includes the steps of measuring a height h of the element-substrate bonding surface from the height reference surface; applying the adhesive to the element-substrate bonding surface; and causing the first surface to oppose the element-substrate bonding surface with the adhesive being provided therebetween, and disposing the second surface at a predetermined height m from the measured height h to harden the adhesive at a portion between the element-substrate bonding surface and the element substrate.
