The nozzle is characterized in that at least one recess (3) is provided at the front end (1B) in which the channel exits (2A, 2A′) are positioned. Disclosed is also a method for the fabrication of a nozzle body as defined above, use of such a nozzle in an inhalation device for nebulizing a liquid, and an inhalation device for nebulizing a liquid into a respirable aerosol, comprising such a nozzle.
