There is provided a backflush needle allowing maintaining the shape of a soft member at the tip when passing through a cannula. A backflush needle (10) of the present invention is used in an ophthalmic operation with the backflush needle passed through a cannula attached to an eyeball. The needle includes a tubular needle main body (11) to pass through the cannula, a tubular soft member (20) connected to a front end of the needle main body (11), and a rod-shaped core member (21) to pass through respective tubular hollow cavities of the needle main body (11) and the soft member (20). The core member (21) is axially movable, allowing protrusion of a front end of the core member (21) from the soft member (20) and retraction of the same until a position detached from the needle main body (11).
