Summary:PROBLEM TO BE SOLVED: To provide a conductive particle which, when used in anisotropic conductive adhesive, can obtain stable connection resistance, and can also improve insulation reliability.SOLUTION: A conductive particle 10 comprises a core particle 2, and a conductive outermost layer 5 surrounding the core particle 2. The outermost layer 5 is formed by sputtering method. The outermost layer 5 has a plurality of protrusions 5a formed on its outer surface. 【課題】異方導電性接着剤に用いられたときに、安定した接続抵抗を得るとともに、絶縁信頼性の更なる改善を図ることのできる導電粒子を提供する。【解決手段】コア粒子２と、コア粒子２を囲む導電性の最外層５と、を備える導電粒子１０。最外層５が、スパッタ法により形成された層である。最外層５は、その外側表面に形成された複数の凸部５ａを有している。【選択図】図１
