PROBLEM TO BE SOLVED: To simply and appropriately supply a desired, very small amount of liquid without any disadvantages in terms of cost. SOLUTION: In the apparatus for supplying a very small amount of liquid provided with a nozzle drive system 8 for moving a nozzle 2 at least in two directions, and at the same time sucking and discharging liquid by the nozzle 2, and a control means 7 for controlling the operation of the nozzle by the nozzle drive system 8, discharging a very small amount of liquid from a tip section 20 of the nozzle 2 into a container 5 where liquid 30 is retained to supply the liquid, a nozzle drive system 8 is configured so that after the nozzle 2 is moved down from the upper position of the container 5 and a tip 20a of the nozzle 2 is stopped at a first fixed position P1 that is set into the liquid 30 based on control by the control means 7, the tip 20a of the nozzle 2 is stopped at a second fixed position P2 that is set into the liquid 30 by moving up the nozzle 2, and a very small amount of liquid is discharged into the liquid 30 from the tip section 20 of the nozzle 2. |
