Abstract

The present invention provides a rhenium tungsten wire comprising 10 to 30 mass % of rhenium and balance of tungsten, and having a wire diameter D of 0.10-0.40 mm, wherein a tensile strength T (N/mm) of the rhenium tungsten wire exists within a range specified by an equation (1).6314.6−7869.34516.3≦5047.4−7206.4+5129.2  (1).In a case where the medical needle is manufactured from the above rhenium tungsten wire, crack and breakage hardly occur at a time of performing a pressing work or a bending work, so that a production yield and durability of the resultant products can be greatly improved.
