By moving the actuating member 9 fitted with the push-down head 8 up and down with respect to the cylinder, the liquid inside the container is moved to the nozzle 7 of the push-down head 8.
In the liquid ejector provided so as to eject from above, an air chamber 21 is formed between the head top wall 10 and the cap top wall 18 by air-tightly fitting the elastic cap 17 to the upper end portion of the pressing head. Further, an air circulation hole 16 is bored in a portion of the head top wall 10 above the cylinder hole of the stem fitting cylinder 11 in which the base end of the nozzle hole is opened, and the stem fitting hole and the air chamber 21 are communicated with each other.
