Abstract

Disclosed is a conductive fine particle having low resistance and excellent connection reliability. Also disclosed is an anisotropic conductive material. Specifically disclosed is a conductive fine particle composed of a base fine particle, a nickel layer formed on the surface of the base fine particle, and a gold layer formed on the surface of the nickel layer. This conductive fine particle is characterized in that the nickel content in a part of the gold layer within 5 nm from the outermost surface is not more than 4% by weight.
