A prefilled syringe that allows a user to recognize that the liquid-drug is completely discharged at approximately the same moment.A prefilled syringe (1) includes: an syringe barrel (10) having a liquid-drug discharge portion on the distal end and an opening (39) on the proximal end； a cap (21) sealing the liquid-drug discharge portion； a gasket (43) inserted in the syringe barrel body (40) ； a plunger (50) that includes a shaft portion (51) and a pressing portion (54) located on the proximal end of the shaft portion (51) and slides the gasket (43)； and a liquid-drug (100) stored between the liquid-drug discharge portion and the gasket (43) in the syringe barrel body (40) and discharged from the liquid-drug discharge portion. The prefilled syringe includes an upraised portion (36) located on an inner wall of the syringe barrel (10) between the gasket (43) and the opening (39) and including a step (36a) rising in an approximately perpendicular direction, and a clicker (60) protruding from the shaft portion (51) to slide against the upraised portion (36) with movement of the gasket (43) and flexes in an approximately perpendicular direction, the clicker (60) being configured to be flipped by crossing over the upraised portion (36) to generate a clicking sound and/or a clicking vibration in response to completion of the discharge of the liquid-drug (100).
