PROBLEM TO BE SOLVED: To provide a gasket for an exterior-wall joint section capable of being easily inserted and installed accurately regardless of the size of the joint width of the exterior-wall joint section. SOLUTION: In the gasket 20 for the exterior-wall joint section, the first cutoff lip sections 22, the second cutoff lip sections 23, the third cutoff lip sections 24 and the first crosslinking sections 25 projected along both side faces of a support section, a leg section 26 formed by slightly expanding the lower end of the support section, the second crosslinking sections 27, and insert-molded mandrel materials 1P are molded integrally respectively. Since the first crosslinking sections 25 and the second crosslinking sections 27 are molded under the state in which approximately intermediate sections are bent towards the opposite direction of the support section, sections near to the front end sections of the first cutoff lip sections 22 are curved and deformed by comparatively large curvature radii by bending deformation with insertion to the exterior-wall joint section J in the first crosslinking sections 25, and the first spaces SP1 are buried and the flexural rigidity of the second cutoff lip sections 23 is reinforced, and the second spaces SP2 are buried and the flexural rigidity of the second and third cutoff lip sections 23, 24 can be reinforced by bending deformation with insertion to the exterior-wall joint section J in the second crosslinking sections 27.
