Provided is a quantitative cell dispensing apparatus using liquid droplet manipulation, for quantitatively dispensing cells from hydrophilic suspension containing a plurality of cells. The quantitative cell dispensing apparatus includes hydrophilic suspension, a liquid droplet manipulation unit, a dispensing unit, a sensing unit, and a control unit. The hydrophilic suspension includes a plurality of cells and electrolyte, and the liquid droplet manipulation unit. The liquid droplet manipulation unit includes an inlet and a liquid droplet outlet portion. The dispensing unit discharges a liquid droplet received from the liquid droplet outlet portion to a target portion. The sensing unit optically senses liquid droplets distributed on a panel of the liquid droplet manipulation unit. The control unit analyses the number of cells contained in each liquid droplet using a single sensed by the sensing unit, and controls the liquid droplet manipulation unit to transfer a liquid droplet containing a predetermined number of cells to the liquid droplet outlet portion.
