Abstract
There is provided a liquid formulation ejection device which improves reliability of inhalation even in a case where a preejection is performed and resolves a concern about hygiene. The liquid formulation ejection device () ejects a liquid formulation in a form of liquid droplets into an inhalation flow path () and allows a user to inhale the formulation. The liquid formulation ejection device () includes an ejector () for performing normal liquid droplet ejection for inhalation and liquid droplet preejection not for inhalation, and a discharger () for removing liquid droplets ejected by the liquid droplet preejection out of an inside of the inhalation flow path ().
