PURPOSE: To obtain a quick-curing adhesive composition, capable of remarkably manifesting shortening effects on setting time even for a porous adherend such as Fagus crenata Blume, excellent in storage stability and quickly bonding to various adherends by blending an organotitanium compound expressed by a specific formula therein.

CONSTITUTION: This composition comprises (A) an alkyl α-cyanoacrylate and (B) an organotitanium compound expressed by formula I [R1 to R4 are each a 1-6C alkyl, alkenyl or aryl). For example, the component (A) is expressed by formula II (R is a group without containing an anionic polymerizable group, specifically an alkyl, allyl, phenyl, etc.) and tetramethyl titanate, tetraethyl titanate, tetra-n-propyl titanate, etc., are preferably used as the component (B).
