PROBLEM TO BE SOLVED: To provide an ink flow passage unit capable of stabilizing supply of ink to a recording head.SOLUTION: An inkjet recording device includes an ink flow passage unit 50 connecting together a flow passage R of flow passage members 513, 514 and a connection port 510a of a recording head 510. The ink flow passage unit 50 includes a first pipe member 515 connected to the flow passage member 514, and a second pipe member 515 connected to the connection port 510a. Since the first pipe member 515 is inserted up to a position closer to another opening part 516b than to the longitudinal center of the second pipe member 516, and heat from a heater H disposed in the flow passage member 513 is conducted to the first pipe member 515 via the flow passage members 513, 514, the first pipe member can supply ink flowing in a pipe to a position near the connection port 510a of the recording head 510 in a hot state. |
