METHOD FOR PRODUCING CONDUCTIVE PARTICLES, METHOD FOR PRODUCING INSULATING COATED CONDUCTIVE PARTICLES, AND ANISOTROPIC CONDUCTIVE ADHESIVE FILM

摘要

the present invention the conductive particles on the nickel layer formed below the gold layer with an average film thickness of the outermost layer 300 as the conductive particles having an , element composition ratio of nickel and gold on the surface of the conductive particles by X-ray photoelectron spectroscopy (Ni / Au) is characterized in that not more than 0.4.
