<p>An adhesive sheet not tacky at ordinary temperatures, exhibiting strong adhesion and high heat resistance by heating under low pressure for a short period of time, having no problem of adhesive protrusion in heat adhesion, storable at ordinary temperatures and excellent in aging stability, which comprises a base material having provided on one side or both sides thereof a layer or layers of a thermal adhesive composition comprising a non-tacky polymer prepared from monomers composed of 70% to 100% by weight of a (meth)acrylic ester represented by the following general formula (I), a homopolymer of which has a glass transition temperature of -30 DEG C or more, and 0% to 30% by weight of a monoethylenic unsaturated monomer copolymerizable therewith, based on the total amount of the monomers: <CHEM> wherein R1 represents a hydrogen atom or a methyl group; R2 represents a methylene group, an ethylene group or a propylene group; n is an integer of 1 to 3; and phi represents a phenyl group, a monoalkyl-substituted phenyl group or a dialkyl-substituted phenyl group.</p> |
