Disclosed is an adhesive composition having high adhesive strength with respect to shear, peeling, and impacts, and particularly having an excellent resistance to heating-cooling cycle. This adhesive composition contains (a) a 2-cyanoacrylate ester (2-cyanoacrylate 2-ehoxyethyl or the like) and (b) a polyfunctional cyanoacrylate ester having two or more 2-cyanoacryloyl groups, with the numeric average molecular weight of the polyfunctional cyanoacrylate ester (b) being 1000-50,000 (preferably 2000-30,000), and with the polyfunctional cyanoacrylate ester (b) being 1-400 parts by mass (preferably 1-200 parts by mass) when the 2-cyanoacrylate ester (a) is 100 parts by mass. |
