PURPOSE:To provide a fine Pd wire for semiconductor element composed of such Pd allay as causing no conventional trouble by improving sphericity and high temperature strength of ball within a predetermined compositional range. CONSTITUTION:The inventive fine Pd wire is composed of Pd added with one kind of 0.003-3at% of Ir, 0.003-1at% of Os or 0.003-1at% or Ru, total 2at% or mess or It, Os and/or Ru, or total 1at% or less of Os and Ru and containing inevitable impurities. |
