Reliable ink jet print head, ink jet head cartridge, ink container, and the manufacture method thereof are provided. Specifically, an ink supply opening of an ink container includes a beam member crossing the ink supply opening. The beam member is shaped so that filler material included therein is oriented in a direction along which the beam member extends. By providing the beam member in the ink supply opening of the ink container, the deformation of the ink container due to a temperature change is prevented by the beam member having a smaller linear expansion coefficient that extends in a direction orthogonal to the nozzle arrangement direction. Thus, a more reliable ink jet print head can be provided. In addition, higher strength can be achieved in a direction orthogonal to the nozzle arrangement direction of the ink container.
