Ink jet recording head having substrate and ceiling plate base pressed together by base plate and ink supply member
An ink jet recording head includes a substrate having an element surface provided with energy generating elements, a ceiling plate provided with a grooved surface having grooves to become ink passages, the grooved surface and the element surface being bonded to form the ink passages, a base plate for supporting the substrate from the side opposite the element surface, and an ink supply member in contact with the base plate at a contact portion and having an ink flow path wall face to be communicated with the ink passage. The base plate and the ink supply member pinch the substrate and the ceiling plate at the contact portion as a fulcrum so as to enable the base plate to press the substrate from the side opposite the element surface, and the ink supply member to press the ceiling plate from the side opposite the grooved surface.
