PURPOSE:An adhesive to which a substance emitting fluorescence with X-rays is added as a filler and the components causing photoreactions is excited with the fluorescence to effect curing, thus adhering non-permeable materials without strains at the adhesion sites and cleavage caused by thermal expansion. CONSTITUTION:A substance emitting fluorescence with X-rays such as CaWO4 or CaSiO3:Pb is added as a fillter to excite the components which cause photoreaction by the fluorescence emitted with X-ray such as polyvinyl cinnamate to start the reaction of curing an acrylic or polybutadiene resin which is active to the light of, e.g., about 470nm wavelength.
