PROBLEM TO BE SOLVED: To provide a needle set capable of safely protecting a tip of a metal needle even when the needle cannot be removed after centesis.SOLUTION: A needle set includes: a needle member forming a hollow part inside； a tube member including a tube body that can be moved in the hollow part with respect to the needle member in an axial direction of the needle member. The tube member includes: a lock part capable of locking the needle member, with the tube body located at a prescribed position in the hollow part； and a protection part located radially outside around a distal end of the needle member, with the needle member locked to the lock part.SELECTED DRAWING: Figure 2【課題】穿刺後に針を抜き去ることができない場合であっても、金属針の針先をより保護しやすい針セットを提供することを目的とする。【解決手段】内部に中空部を区画する針部材と、前記中空部内を前記針部材に対して前記針部材の軸方向に移動可能な管本体部を備える管部材と、を備え、前記管部材は、前記管本体部が前記中空部内の所定位置にある状態で、前記針部材を係止可能な係止部を備え、前記針部材が該係止部に係止されている状態で、前記針部材の先端部に対して径方向外側の周囲に位置する保護部が設けられていることを特徴とする。【選択図】図２
