Abstract
Provided is an adhesive composition which exhibits excellent water resistance and warm-water resistance without impairing instantaneous adhesiveness. The 2-cyanoacrylate adhesive composition contains a 2-cyanoacrylic acid ester, and a specific phthalic anhydride derivative, in which the content of the phthalic anhydride derivative is from 0.01 to 5% by mass, relative to the total amount of the adhesive composition. Preferably, the adhesive composition further contains an elastomer.
