Abstract
【解決手段】 発光ダイオード20における配線基板26の裏面には、金属ベース24に接着する接着面に、接着剤36が貫通孔26b内に流れ込むことを防ぐ積層パターン34が設けられている。積層パターン34は、貫通孔26bの縁に沿って形成され且つ金属ベース24と配線基板26との間に挟まれるせき止め部34aと、このせき止め部34aの周囲に形成され且つせき止め部34aより低い接着補強部34bとを有している。積層パターン34のせき止め部34aは、配線基板26と金属ベース24との間に挟まれて広がる接着剤36をせき止めて、貫通孔26b内に流れ込むことを阻止する。積層パターン34の接着補強部34bは、配線基板26の接着面に起伏をつけて表面積を増やすことで接着力を高めている。
