摘要: A conductive resin composition which includes an epoxy resin (A), a compound (B) having a (meth)acryloyl group and a glycidyl group, a phenolic resin curing agent (C), a radical polymerization initiator (D) and a conductive particle (E). The conductive resin composition which may be B-staged (semi-cured) at a relatively low temperature to exhibit sufficient tack-free properties and excellent pressure-sensitive tackiness. This permits temporary bonding of parts without involving solvent evaporation or light illumination, thereby reducing or avoiding an increase in facility costs. The conductive resin composition may thereafter be cured (C-staged) to provide a cured product having a desirable bond strength, while maintaining a low specific resistivity.
