摘要: An adhesive tape comprising a base and, superimposed thereon, an adhesive layer, this adhesive layer comprising an adherent component (A), an epoxy resin (B), a thermally active latent epoxy resin curing agent (C), an energy radiation polymerizable compound (D) and a photopolymerization initiator (E), wherein either or both of the epoxy resin (B) and energy radiation polymerizable compound (D) have a dicyclopentadiene skeleton in its molecule or molecules thereof. The resultant adhesive tape has an adhesive layer which provides reduced water absorption of an adhesive curing product and which enables a lowering of the elastic modulus thereof during thermocompression bonding.
