An object of the present invention is to enhance the inhalation efficiency by bearing liquid droplets on an air flow at the early stage of inhalation in an inhaler that is used for the user to inhale a medicine ejected from an ejection head. According to one embodiment of the present invention, from an operation in which the user lets out a breath before the start of inhalation, that is, from the exhalation stage, a positive pressure B produced by the exhalation is detected by a pressure detecting unit, and is compared with a standard pattern stored in a storage unit, by which the exhalation profile of the user is prepared. A time difference t between the exhalation finish time and the start time of next inhalation is estimated, followed by the determination of the ejection start time T1 based on these pieces of information. |
