Disclosed is a medical needle used for performing a piercing or insertion operation on an object repetitively, the medical needle comprising a needle body and a metallic glass material layer formed on a surface of the needle body, the metallic glass material layer comprising an alloy consisting of aluminum, zirconium, copper and tantalum. With the presence of the metallic glass material layer covering the needle body, the medical needle may maintain its sharpness after having performed multiple piercing or insertion operations to enhance durability, minimize the increase of maximum piercing or insertion force resulted from piercing or insertion operations, and decrease injury to the object caused by piercing or insertion operations.
