Abstract:
1. A thermosetting adhesive or pressure-sensitive adhesive tape or sheet having a structure in which a thermosetting adhesive or pressure-sensitive adhesive layer made of a thermosetting adhesive or pressure-sensitive adhesive composition containing an acrylic polymer (X) containing at least an alkyl(meth)acrylate (a) in which the alkyl moiety thereof has from 2 to 14 carbon atoms, a cyano group-containing monomer (b), and a carboxyl group-containing monomer (c) as monomer components and a phenol resin (Y) is protected by a release liner which does not substantially contain a silicone component, wherein in the acrylic polymer (X), a proportion of the alkyl(meth)acrylate (a) in which the alkyl moiety thereof has from 2 to 14 carbon atoms to the cyano group-containing monomer (b) to the carboxyl group-containing monomer (c) is (60 to 75)/(20 to 35)/(0.5 to 10) by weight in terms of a ratio of component (a)/component (b)/component (c).
