DISPENSER

PROBLEM TO BE SOLVED: To provide a new dispenser capable of being easily connected to fluid channels formed at a thin-plate-like chip and of preventing a sample fluid from leaking. SOLUTION: The dispenser for supplying the sample liquid for the thin-plate-like chip T in which the plurality of fluid channels L are formed inside, includes a fluid injection head 2A and a fluid discharge head 2B for holding the chip T and a holder 1 for connecting both heads. The heads 2A and 2B each includes injection paths 23A and discharge paths 23B, and they each keep one end connected to the fluid channels L of the chip T via a sealing member 30. In the heads 2A and 2B, tapered protrusion parts 29 are each formed at one end opening parts of the injection paths 23A and the discharge paths 23B on the side connecting to the fluid channels L. Recesses 32 for fitting the protrusion parts 29 of the heads 2A and 2B at the part of small holes 31 corresponding to the fluid channels L are formed in the sealing member 30.
