A dispensing device for dispensing a dispensing liquid containing a prescribed substance to a target region, the dispensing device being equipped with a storage unit for storing the dispensing liquid, a drive unit for imparting dispensing energy, a pressurization unit for pressurizing the dispensing liquid stored in the storage unit by using the dispensing energy from the drive unit, and an injection unit for injecting the dispensing liquid that has been pressurized by the pressurization to the target region through an injection port. In addition, during the transition to injection pressure of the dispensing liquid, which corresponds to the generation of the dispensing energy, the pressurization unit pressurizes the dispensing liquid so as to achieve a convergent state of vibrations within a prescribed interval from starting to build pressure during the transition to injection pressure, and in a manner such that the ratio of the initial peak value of a first vibration element to the peak value of another vibration element, which follows the first vibration element in the vibrations within the prescribed period, is greater than 1 and no greater than a prescribed first ratio. As a result, it is possible to reduce invasiveness for the target region when dispensing.La présente invention concerne un dispositif de distribution pour distribuer un liquide de distribution contenant une substance prescrite à une région cible, le dispositif de distribution étant équipé d'une unité de stockage pour stocker le liquide de distribution, d'une unité d'entraînement pour communiquer l'énergie de distribution, d'une unité de pressurisation pour pressuriser le liquide de distribution stocké dans l'unité de stockage par utilisation de l'énergie de distribution de l'unité d'entraînement, et d'une unité d'injection pour injecter le liquide de distribution qui a été mis sous pression par la pressurisation à la région cible par l'intermédiaire d'un orifice d'injection. De plus, pendant la t
