CONDUCTIVE FINE PARTICLE, METHOD FOR PRODUCING CONDUCTIVE FINE PARTICLE AND ELECTROLESS SILVER PLATING LIQUID

摘要

It is an object of the present invention to provide a conductive fine particle which can prevent conductive defects and makes it possible to reduce the connection resistance, a method for producing the conductive fine particle, and an electroless silver plating liquid used for the producing of the conductive fine particle. The present invention is directed to a conductive fine particle, which comprises: a base particle; a base layer made of nickel on the surface of the base particle; and a silver layer formed by electroless silver plating on the surface of the base layer, the purity of silver in the silver layer being 90 wt % or more.
