PROBLEM TO BE SOLVED: To provide an inkjet recording head cartridge that can stably supply a large flow rate of ink. SOLUTION: The inkjet recording head cartridge has a discharge circuit section 1 discharging ink, an ink container 3 holding the ink, and a channel 6 guiding the ink to the discharge circuit section 1 from the ink container 3. A groove-shaped channel 10 narrower than the entirety of the channel 6 continuously extends from the ink container 3 to the discharge circuit section 1 on the inner wall of the channel 6. The channel 6 has a horizontal portion 6b. A constricted section 11 narrowing toward the supply direction of the ink is formed in the horizontal portion 6b. A sloped portion 12 becoming higher in the direction of separation from the discharge circuit section 1 is provided in the ceiling section of the horizontal portion 6b.
