According to one embodiment, a tungsten wire including a tungsten alloy containing rhenium, wherein, according to an EBSD analysis on a unit area of 40 μm× 40 μm in a central portion located within 100 μm concentrically extending from a central axis in a cross section along a wire radial direction perpendicular to a wire drawing direction in a main body portion of the tungsten wire, an area ratio accounted for by crystal orientations having an orientation difference of 15 degrees or less from <101>, which is parallel to the wire drawing direction, to a measurement field is 90% or more and 99.9% or less on an IPF map.
