In the intradermal needle (10) having a needle tube (14) that can be punctured into a living body, a packaging article (12), and an injection device (18), a pivotable protector (80) is provided to a wide diameter part (30). The protector (80) has an arm (84) that can pivot around an axle of pivoting, and a lid (82b). The pivoting axle part is provided to the wide diameter part (30), and the lid (82b) is formed to give a width smaller than a diameter of the wide diameter part (30). The arm (84) keeps the lid (82b) in the open position away from the pivoting axle part and closer to an axis of the needle hub (16).
