Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dispensing system for effectively reducing occurrence of liquid dripping and air gaps. SOLUTION: The dispensing system 10 includes: a nozzle tip 30; a moving mechanism 20 for moving the nozzle tip 30; a dispensing pump 16 for executing suction and discharge of liquid by varying internal pressure of the nozzle tip 30; a storage part 25; and a control part 24 for controlling drive of the moving mechanism 20 and the dispensing pump 16. The storage part 25 stores air suction conditions including an air suction speed for canceling an increase in internal pressure following evaporation of liquid generated in the nozzle tip as air suction setting information during a period from completion of suction of liquid by the nozzle tip 30 to start of discharge of liquid. The control part instructs the dispensing pump 16 to perform air suction under air suction conditions prescribed in the air suction setting information during a period from the completion of suction of liquid by the nozzle tip 30 to start of discharge of liquid.
