Method of manufacturing an ink jet head

摘要

A method for manufacturing an inkjet head, which jets, by shear deformation of a partition wall, an ink in an ink flow path. The method includes the steps of: forming a metal electrode on a surface of the partition wall; coating an adhesive agent on the cover board; superposing the cover board onto an upper end surface of the partition wall under a condition wherein the hardness of the adhesive agent is not less than 10⁵ dyne/cm², so that the ink flow path is formed with the partition wall and the cover plate; and pressing the channel board and the cover board under the hardness condition wherein the hardness of the adhesive agent is not less than 10⁵ dyne/cm² and not greater than 10⁹ dyne/cm².
