Abstract
The present invention is a metallic wire rod comprising iridium or an iridium-containing alloy and, the wire rod has in the cross section thereof biaxial crystal orientation of 50% or more of abundance proportion of textures in which crystallographic orientation has preferred orientation to <100> direction. In the present invention, crystal orientation in the outer periphery from semicircle of the cross section which is the periphery of the wire rod is important, and in this zone, abundance proportion of textures in which crystallographic orientation has preferred orientation to <100> direction is preferably not less than 50%.
