PROBLEM TO BE SOLVED: To provide an adhesion method of various adherends, using a 2-cyanoacrylate-based adhesive composition, which is substantially free from the diffusion of formaldehyde from adherend to the environment without injuring performances such as quick-curing property, stability and adhesive property, which are inherent in a 2-cyanoacrylate-based adhesive composition itself. SOLUTION: The adhesion method comprises adhering various adherends by using cyanoacrylate-based adhesive composition mainly composed of 2-cyanoacrylate and then treating the surface of the adhesive layer with a surface treating agent, wherein the various adherends are adhered by using a 2-cyanoacrylate-based adhesive composition causing≤0.1 mg/L diffusion amount of formaldehyde from the adherend treated with the surface treating agent, per 0.5 g adhesive composition, which diffusion amount is measured by a method in accordance with JIS K5601-4-1 (2003).
