摘要：
An injection device for injecting an injection liquid containing a prescribed substance into a target region the injection device being equipped with a storage unit for storing the injection liquid a drive unit for imparting injection energy a pressurization unit for pressurizing the injection liquid stored in the storage unit by using the injection energy from the drive unit and an injection unit for injecting the injection liquid that has been pressurized by the pressurization into the target region through an injection port. In addition during the pressure transition of the injection liquid at the injection port a convergent state of vibrations is achieved during the pressure transition within a prescribed interval from starting to build pressure and initial first vibration element pressure during the vibrations within the prescribed interval reaches a peak value thereof at a prescribed speed or the vibrations within the prescribed interval are of a frequency that belongs to a prescribed frequency range. As a result it is possible to reduce invasiveness for the target region when performing an injection.
