PROBLEM TO BE SOLVED: To reduce variation in concentration of delivered suspension in an apparatus for suspension dispensing capable of intermittently performing dispensing operation of the suspension. SOLUTION: The apparatus for suspension dispensing comprises a liquid transportation pipe 2 for sucking the suspension 4a stored by a suspension reservoir section 4 from one end side and delivering it from a nozzle 7 disposed at the other end side, a pressurizing member 3 for pressurizing the liquid transportation pipe 2 to form a blocked section 8, and a driving section 9 for moving the pressurizing member 3 to vary the position of the blocked section 8. The dispensing operation of moving the pressurizing member 3 so as to approach the nozzle 7 and delivering the cell suspension 4a from the nozzle 7 is performed. When the dispensing operation is not performed, the pressurizing member 3 is moved so as to back away from the nozzle 7, and the suspension 4a remaining in the liquid transportation pipe 2 is moved to the suspension reservoir section 4 side.
