Abstract
An ink jet recording head manufacturing method for manufacturing ink jet recording head having an ink passage, wherein a droplet of ink is ejected through the passage from an ink ejection outlet at an end of a passage onto a recording material. Ions are injected into a surface having the ink ejection outlet to change a surface property of the surface.
