An inhaling apparatus is to be used by a user to inhale a liquid medical agent from an inhalation port thereof. It has a liquid medical agent ejecting section having an ejection port for ejecting a liquid medical agent as droplets and a pressure detecting section for detecting the negative pressure produced by the atmospheric pressure as pressure difference at the time of inhalation of the user for the purpose of controlling the ejection of droplets from the ejection port. The ejection port of the liquid medical agent ejecting section is arranged at a position adapted to produce a pressure difference smaller than the pressure difference with the atmospheric pressure as detected by the pressure detecting section at the time of the inhaling action of the user.
