Disclosed is a medical needle that maintains its sharpness even after repeated penetrating operations. A medical needle 1 that repeatedly performs a penetrating operation on an object, which includes a needle body 10 and a metal glass material layer 20, and the metal glass material layer 20 is formed on the surface of the needle body 10. Includes alloys of aluminum, zirconium, copper and tantalum. By covering the needle body 10 with the metal glass material layer 20, the sharpness of the medical needle 1 is maintained even after a plurality of penetration operations using a medical needle, and the number of penetration operations is reduced. The increase in the maximum penetration force applied to the medical needle 1 due to the increase is reduced, the durability is improved, and the damage to the object due to the penetration operation is reduced. [Selection] Figure 1【課題】繰り返しの穿通操作後であっても鋭さが維持される医療用針を提供する。【解決手段】対象物に繰り返して穿通操作を行う医療用針１であって、針本体１０及び金属ガラス材料層２０を含み、金属ガラス材料層２０は、針本体１０の表面に形成され、且つアルミニウム、ジルコニウム、銅及びタンタルからなる合金を含む。金属ガラス材料層２０で針本体１０を被覆することにより、医療用針を用いて複数回の穿通操作を行った後であっても、医療用針１の鋭さが維持され、穿通操作の回数の増加による医療用針１に加える最大穿通力の増加が低減され、耐用性が向上され、穿通操作による対象物への損傷が低減される。【選択図】図１
