CONDUCTIVE PARTICLES AND METHOD AND DEVICE FOR MANUFACTURING THE SAME, ANISOTROPIC CONDUCTIVE ADHESIVE AND CONDUCTIVE CONNECTION STRUCTURE, AND ELECTRONIC CIRCUIT COMPONENTS AND METHOD OF MANUFACTURING THE SAME

An electrical connection is formed by using a double laminated conductive fine particle provided with a conductive metal layer on the surface of a spherical elastic base particle by electroless plating and electroplating and a layer of a low-melting-point metal on the surface of the conductive metal layer and wherein the conductive metal layer comprises a plurality of metal layers.
