Abstract

An adhesive composition comprising 10 to 60 parts by weight per 100 parts of the total weight of components (1) to (4) of a monofunctional (meth)acrylic monomer, 0.01 to 10 parts by weight per 100 parts of the total weight of components (1) to (4) of a compound having at least two (meth)acryloyl groups in a molecule, 30 to 80 parts by weight per 100 parts by weight of the total weight of components (1) to (4) of a heat resistant epoxy resin, 0.1 to 20 parts by weight per 100 parts by weight of the total weight of components (1) to (4) of an imidazole compound, 0.001 to 10 parts by weight per 100 parts by weight of the total weight of components (1) to (4) of a photopolymerization initiator, and 0.01 to 20 parts by weight per 100 parts by weight of the total weight of components (1) to (4) of a thixotropic agent, with which an electronic part can be effectively packaged to a printed board.
