An insulated conductive particle for an anisotropic conductive film is disclosed. One embodiment of the particle includes a conductive particle and insulating fixative particles discontinuously fixed on the surface of the conductive particle. The insulating particles provides insulation with other adjacent insulated conductive particles, while the insulated conductive particle is electrically connected between electrodes with the insulating fixative particles being deviated from its position. The instant disclosure also provides a method for manufacturing the insulated conductive particle, an anisotropic conductive adhesive film containing the insulated conductive particles, and an electrically connected structure using the film.
