Description
上記実施の形態に記載の端子構造は、板状の端子を曲げて形成した半導体モジュールの端子構造であって、前記端子の一方の板面には、曲げられたときに外側の曲面に相当する所定領域に複数の凹形状又は複数の凸形状の少なくとも一方を含む凹凸形状が形成されたことを特徴とする。この構成によれば、一方の板面の所定領域の表面積が凹凸形状によって増加されている。よって、端子が曲げられたときに外側の曲面に相当する所定領域に引張応力が強く作用するが、所定領域の表面積の増加分だけ曲げの外側で伸びが許容される。表面積の増加分が板面の伸びに使用されることで、一方の板面に亀裂が入ることが防止されて、端子腐食の進行及び電気抵抗の増加を抑えつつ、端子を良好に曲げることができる。
