Abstract:
1. A method for producing a joined structure, the method comprising: pressure-bonding first and second circuit members together via an anisotropic conductive film while the circuit members are being heated, to thereby join the circuit members with each other, wherein the anisotropic conductive film electrically connects the first circuit member with the second circuit member having a nitrogen atom-containing film on a surface thereof facing the first circuit member, wherein the anisotropic conductive film comprises a first layer which is to be located at a first circuit member side, and a second layer which is to be located at a second circuit member side, wherein the first layer comprises a cationic curing agent and a first thermosetting resin, and the second layer comprises a radical curing agent and a second thermosetting resin, wherein at least one of the first and second layers comprises conductive particles, and the difference in maximum exothermic peak temperature between the first and second layers is within the range of 0 to 20° C., and wherein the first thermosetting resin is an epoxy resin and the second thermosetting resin is an acrylic resin.
