An adhesive sheet not tacky at ordinary temperatures,nexhibiting strong adhesion and high heat resistance by heatingnunder low pressure for a short period of time, having no problemnof adhesive protrusion and excellent in storage stability,nwhich comprises a base material having provided on one side ornboth sides thereof at least one layer of a thermosettingnadhesive comprising (1) a non-tacky polymer of a monomer mixturencomprising from 70% to 99% by weight of a (meth)acrylic esternrepresented by formula (I), a homopolymer of which has a glassntransition temperature of -30°C or more, and from 1% to 30% bynweight of a monoethylenic unsaturated monomer beingncopolymerizable therewith and having a functional group capablenof reacting with an epoxy resin each based on the monomer mixturenand (2) from 5 parts to 30 parts by weight of the epoxy resinnper 100 parts by weight of the monomer mixture, and notnsubstantially comprising a curing agent for the epoxy resin: |
