[Problem] To provide: a conductive adhesive which contains an epoxy (meth)acrylate resin and which can form a bonded zone that is not susceptible to being deteriorated by halogen; an anisotropic conductive film; and electronic devices using both. [Solution] A conductive adhesive and an anisotropic conductive film which each contain a conductive filler and a binder resin, wherein: the binder resin comprises an epoxy (meth)acrylate resin that is a product of addition reaction of (meth)acrylic acid and an epoxy compound having a sum of total chlorine atom concentration and total bromine atom concentration of 300 massppm or less, preferably 50 massppm or less; and the conductive filler is dispersed in the binder resin which comprises such an epoxy (meth)acrylate resin. The epoxy (meth)acrylate resin is preferably prepared by subjecting a starting compound (substrate) having a carbon-carbon double bond to epoxidation of the double bond with an oxidizing agent consisting of hydrogen peroxide, and then subjecting the obtained epoxy compound to addition reaction with (meth)acrylic acid.
