This anisotropic electroconductive film in which a decrease in adhesiveness due to moisture is suppressed and which has excellent storage stability is an anisotropic conductive film in which electroconductive particles are dispersed in an insulating adhesive, the anisotropic conductive film containing 1-20 wt% and preferably 5-15 wt% of a zeolite. The average micropore diameter of the zeolite is 3-5 angstroms, and the average particle diameter of the zeolite is smaller than the average particle diameter of the electroconductive particles. Preferably, the former is 10%-80% of the latter. Specifically, the average particle diameter of the zeolite is preferably 0.1 [mu]m-8 [mu]m, and the average particle diameter of the electroconductive particles is 1 [mu]m-10 [mu]m. |
