Ink jet printing head, manufacturing method therefor, and ink jet printing apparatus
 A method for producing an ink jet printing head comprising a substrate having plural discharge energy generating elements for generating energy to be utilized for discharging an ink and a ceiling plate of a resinous material to be joined to the substrate to constitute, between the ceiling plate and the substrate, ink paths including discharge openings for discharging the ink and plural grooves communicating with the discharge openings and formed in positions corresponding respectively to the discharge energy generating elements is provided which comprises the steps of preparing the substrate provided with the plural discharge energy generating elements, positioning and contacting the ceiling plate and the substrate in such a manner that the discharge energy generating elements are respectively positioned in the grooves, and thermally fusing the contacting portions of the ceiling plate with the substrate while pressing the substrate and the ceiling plate in the positioned state, thereby joining the substrate and the ceiling plate.
