In view of the fact that with the recent rapid progress and development of electronic equipment, further reduction in the connection resistance of conductive fine particles used as anisotropic conductive materials has been demanded, conduction failure prevention The present invention also provides conductive fine particles capable of reducing the resistance value and anisotropic conductive materials. A conductive fine particle comprising a substrate fine particle and a conductive layer made of nickel formed on the surface of the substrate fine particle, the conductive layer having protrusions on the surface, and At least the projections are conductive fine particles containing aluminum and / or zinc.
