PURPOSE:To provide the titled pressure-sensitive adhesive having excellent adhesion wherein a chemically curable component and a photo-curable component penetrate into each other to form a network structure, consisting of a chemically curable component and a photo-curable component. CONSTITUTION:The titled pressure-sensitive adhesive contains a non-photopolymerizable epoxy resin (e.g. bisphenol A type epoxy resin) or an isocyanate compd. (e.g. tolylene diisocyanate) (A) and a hardener (e.g. diethylenetriamine for epoxy resin or ethylene glycol for isocyanate compd.) and a compd. contg. at least two photopolymerizable vinyl groups per molecule and having a vinyl equivalent of 78-700 [e.g.; di-, tri- or tetraethylene glycol di(meth)acrylate] (B). The adhesive contains a chemically curable component and a photo-curable component, these components penetrate into each other and a networ structure is formed thereby so that the adhesive can exhibit excellent adhesion.
