PROBLEM TO BE SOLVED: To enhance the dischargeability of color-mixed ink in an ink storage chamber by securing the smooth flow of ink in the ink storage chamber. SOLUTION: This ink storage chamber 41 comprises: an ink inlet 41b; an ink outlet 41c; an intermediate wall part 34 and a flexible film 61, parallel to and facing the flow direction of the ink flowing toward the ink outlet from the ink inlet; and a peripheral side wall part 41a which surrounds the periphery of a space between the intermediate wall part 34 and the flexible film 61. The intermediate wall part 34 has a pair of flow straightening ribs 41d and 41e which are protruded toward the film 61 and elongated in parallel with the flow direction at an interval between the flow straightening ribs and the film 61.
