Abstract
According to one embodiment, a rhenium-tungsten alloy wire which is a wire including a tungsten alloy containing rhenium. A ratio W/Re of an atomic concentration (atm %) of tungsten (W) to an atomic concentration (atm %) of rhenium (Re) according to XPS analysis is 2.5 or more in an arbitrary measurement area of a unit area having a diameter of 50 μm at a wire surface. A medical needle according to the embodiment includes the rhenium-tungsten alloy wire according to the embodiment.
