It provides an adhesive composition that has flexibility and exhibits excellent adhesion durability. (a) 2-cyanoacrylic acid ester, (b) a polymer having a hydrolyzable silyl group, (c) an elastomer, and (d) an acid catalyst, and the components (b), (c) and (d) When the content of the (a) component is 100 parts by mass, the (b) component is 5 to 200 parts by mass, the (c) component is 5 to 50 parts by mass, and the (d) component is 0.0005 to 0.5 parts by mass. Adhesive composition. In addition, it is preferable to contain 0.001 to 5 parts by mass of the onium salt (e) when the component (a) is 100 parts by mass. |
