摘要： The present invention provides a print head that ejects ink supplied through an ink supply port so as to prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.

摘要： An ink jet recording head is provided with one heat generating member in each of ink flow paths, and the discharge port thereof is arranged on the extended line extending in the normal direction from the center of the main surface of the heat generating member to the surface of the substrate. Then, on the surface of the substrate, non-bubbling area is provided on the center within the projected area having the discharge port projected thereon. Bubble brought to the boil by the heat generating member pushes out ink from the discharge port by the pressure exerted by the bubble, while being communicated with the outside. With the structure thus arranged, it is made possible to enhance the precision of discharge direction of the liquid droplet discharged from the discharge port.
