PROBLEM TO BE SOLVED: To make it easy to control air quantity stored in one of the space portions by making air positively flow into one of the space portions when a space portion for storing air separated from an ink is divided into two. SOLUTION: An ink flowing out from one ink exit port 41c is guided to two ink guide out paths 51Ya, 51b via an ink guide path section 48Y and supplied to a recording head from both the ink guide out paths. A protruding rib 49 regulating the flow of air to the ink guide out path 51Ya hangs from and formed in the ink guide out path 51Ya side in the lower face of the ceiling face of the ink guide path section 48Y. The gap allowing the ink to flow is formed between the lower end of the protruding rib 49 and the bottom face of the ink guide path section 48Y. That is, the protruding rib 49 regulates the flow of air to the ink guide out path 51Ya side but is positioned so as to form the gap allowing the flow of the ink to the ink guide out path in the lower section.
