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.
