Abstract:
An ink jet recording head has sufficient and uniform ink refill for all orifices and separate flow paths even though the substrate has high rigidity by dividing a supply port into a plurality of ports. The substrate of the ink jet recording head has a plurality of separate flow paths corresponding to discharge pressure generating elements, a common flow path communicating with the separate flow paths, an ink supply port communicating with the common flow path and supplying ink to the common flow path, and a plurality of beam portions dividing the ink supply port. A recess is formed on the common flow path, extending to the separate flow paths formed nearest to the beam portion.
