PROBLEM TO BE SOLVED: To provide an ink jet recording head capable of improving the sealing reliability of an ink guiding outlet portion without enlarging a structure of an ink guiding outlet when an ink guiding-out member is inserted, and reducing a rise of a pressure loss at a high flow.SOLUTION: An ink jet recording head is mounted with an ink guiding-out member which is inserted in an ink storage container having an ink guiding outlet for guiding out ink from the inside of the ink storage container, a sealing member for preventing the communication between the inside of the ink storage container and atmosphere at the ink guiding outlet, and an elastic member installed in the ink guiding outlet. The ink guiding-out member is a hollow shape, and a tip end outer peripheral shape has two protrusions.SELECTED DRAWING: Figure 8 |
