ABSTRACT:
It is the object of the present invention to provide a conductive particle which has excellent adhesion between a base particle and a conductive layer, a conductive layer being resistant to breaking, impact resistance being improved, and an anisotropic conductive material using the conductive particle. The prevent invention is a conductive particle, which comprises a base particle and a conductive layer formed on a surface of said base particle, said conductive layer having a non-crystal nickel plating layer in contact with the surface of said base particle and a crystal nickel plating layer, and a proportion of a nickel crystal grain aggregate oriented in a nickel (111) plane derived from an integrated intensity ratio in X-ray diffraction measurement being 80% or more.
