PROBLEM TO BE SOLVED: To provide a cyanoacrylate-based adhesive composition giving high adhesion speed and adhesive strength without using any accelerator including an amine compound in bonding a meshy material and a substrate to each other. SOLUTION: The cyanoacrylate-based adhesive composition comprises (A) 100 pts.wt. of 2-cyanoacrylate, (B) 0.0001-0.001 pt.wt. of at least one compound selected from fluoroboric acid (HBF<SB>4</SB>), boron trifluoride diethyl ether complex (BF<SB>3</SB>-O(C<SB>2</SB>H<SB>5</SB>)<SB>2</SB>) and sulfur dioxide (SO<SB>2</SB>) and (C) 0.001-0.1 pt.wt. of a hydroxy compound represented by formula (1) (wherein, r is 2 or 3; and R is H, a straight-chain or branched alkyl or alkoxyalkyl). This adhesive composition gives excellent quick curability and high adhesive strength in bonding a meshy material and a substrate to each other without using any amine compound.
