PROBLEM TO BE SOLVED: To provide an electric dispenser capable of avoiding delay of time from driving of an air pump to ejection of a content liquid even when a residual amount of the content liquid becomes smaller, and stably ejecting a prescribed amount of the content liquid.SOLUTION: An electric dispenser includes an ejection container 21 mounted on a dispenser body 11, and ejects a content liquid by air supplied from the dispenser body 11. The ejection container 21 comprises a container body 22 having a liquid storage part 23 capable of reducing its volume, and an ejection mechanism 24 of the content liquid. The dispenser body 11 comprises a volume-reduction drive part 13, a sensor part 14 and a control part 15. The control part 15, when the content liquid stored in the ejection container 21 is reduced, performs such control that a liquid level of the content liquid is held at a prescribed height position detected by the sensor part 14 by driving the volume-reduction drive part 13 to reduce the volume of the liquid storage part 23.
