Abstract
【解決手段】最終の塑性加工を経た銀線20を700℃以上融点未満の処理温度T1にまで昇温する。その後、銀線20を700℃以上融点未満の処理温度T1に維持しつつ、銀線20の周辺を排気により真空雰囲気とした後、ヘリウムガスおよび水素ガスを供給して混合雰囲気とする雰囲気交換を3回以上繰り返す。その後、昇温工程の時間と加熱維持工程の時間との合計時間の2倍以上の時間をかけて銀線20を徐冷する。これにより、銀線20の組織全体を粗大化した再結晶粒とすることができ、その再結晶粒の粒界にはヘリウム分子および水素分子のうちの少なくともいずれか一方が充填される。その結果、銀線20に高い電導効率を付与することができる。
