  • Publication number: 20120104333
    Abstract: [Problem to be Solved] To provide conductive particles which are capable of providing an anisotropically conductive adhesive that can maintain sufficient insulation characteristics and conduction characteristics even when used for the connection of a very small circuit, while having excellent moisture absorption resistance at a lower cost. [Solution] A coated conductive particle (5) comprises: a composite conductive particle (3) that has a resin particle (4) and a metal layer (6) that covers the resin particle (4); and insulating fine particles (1) that are provided on the outer side of the metal layer (6) so as to partially cover the surface of the metal layer (6). The metal layer (6) has a nickel-palladium alloy plating layer (6a).
