Abstract:
A multilayer anisotropic electroconductive adhesive comprising:an anisotropic electroconductive adhesive layer comprising a film-forming resin and electroconductive particles and having a melt viscosity at 150.degree. C. of at least 100 poise, the electroconductive particles are coated with an insulating resin that is insoluble in the anisotropic electroconductive adhesive, have a diameter of 2-7 .mu.m and are contained in the anisotropic electroconductive adhesive layer in an amount of 5-60 vol %;an insulating adhesive layer laminated to at least one side of the anisotropic electroconductive adhesive layer, the insulating adhesive layer comprising a latent curing agent and a resin exhibiting setting properties and having a melt viscosity at 150.degree. C. of less than 100 poise.
