PROBLEM TO BE SOLVED: To provide a needleless syringe capable of more easily applying injection to an injection target area having a relatively hairy surface.SOLUTION: A needleless syringe 1 comprises: a housing 2 that forms a shell container of the needleless syringe 1 a nozzle part 6 that has an emitting port 6b formed for emitting an objective injection substance and a first projection member 8 that is provided at the housing 2, has a tip 8a projecting from the emitting port 6b toward an emission direction of the objective injection substance and exposes a contact position to be contacted by the emitting port 6b when a movement of the tip 8a along the surface of an injection target area inclines hair on a surface of the injection target area to the moving direction. The first projection member 8 deforms while maintaining an inclined state of the inclined hair when the emitting port 6b is moved close to the contact position, and then projects the emitting port 6b from the tip 8a of the first projection member 8 toward the emission direction.
