Abstract

A needleless syringe comprises a main syringe body which is a main body thereof and which has, in the main body, a sliding movement passage connected to an opening provided on a front end surface of the main body; a holding unit which has an accommodating unit for accommodating an injection objective substance so that the injection objective substance is releasable; and a driver that is configured to apply energy to the holding unit in order to allow the holding unit to slide toward the opening. When the energy is applied by the driver to the holding unit disposed at the initial position, the holding unit slides in the sliding movement passage to abut against the opening at the abutment position, and thus the injection objective substance accommodated in the accommodating unit is discharged via the opening. Accordingly, the high injection performance of the needleless syringe is appropriately exhibited.
