The inner needle comprises, on a distal side, a blade surface that is inclined with respect to a center axis of the inner needle. The tapered portion covers a proximal end portion of the blade surface in an assembled state in which the inner needle is located in the inner cavity, and an inner shape of a distal-most end of the tapered portion conforms to the blade surface.
