Anisotropic conductive adhesive

摘要

An anisotropic conductive adhesive including conductive particles dispersed in an epoxy-based adhesive containing an epoxy compound and a curing agent gives a cured product having the elastic modulus satisfying the expressions (1) to (5), in which EM35, EM55, EM95, and EM150 are values of the elastic modulus of the cured product at 35° C., 55° C., 95° C., and 150° C., respectively, ΔEM55-95 is the rate of change in the elastic modulus between 55° C. and 95° C., and ΔEM95-150 is the rate of change in the elastic modulus between 95° C. and 150° C.,

1. An anisotropic conductive adhesive comprising:
an epoxy-based adhesive containing an epoxy compound and a curing agent in an amount of 80 to 120 parts by mass based on 100 parts by mass of the epoxy compound; and conductive particles dispersed in the epoxy-based adhesive, wherein the following expressions (1) to (5) are satisfied, in which EM35, EM55, EM95, and EM150 are values of an elastic modulus of a cured product of the adhesive at 35° C., 55° C., 95° C., and 150° C., respectively, ΔEM55-95 is a rate of change in the elastic modulus between 55° C. and 95° C., and ΔEM95-150 is a rate of change in the elastic modulus between 95° C. and 150° C.,
