It includes that the needle-like tubular member having an acuminate needle portion as a free end portion thereof, in which a medicinal liquid can flow, is inserted in the lumen of a tubular main body insertable in a body of a living being, and a protection member having a flexible portion provided in a state such that the protection member is movable together with the needle-like tubular member and such that the flexible portion is interposed between an inner circumferential surface of the lumen and a tip of the needle portion of the needle-like tubular member.
