Abstract
According to one embodiment, a rhenium-tungsten alloy wire is a wire made of a tungsten alloy containing rhenium. The amount of NH4 at a wire surface is 10 massppm or less, and is according to a ratio of a weight of NH4 ions at a wire surface to a weight of an alloy wire (a weight of NH4 ions at a wire surface/a weight of an alloy wire). According to the embodiment, a medical needle and a probe pin include the rhenium-tungsten alloy wire according to the embodiment.
