Abstract
A two-pack type curable adhesive composition includes a base containing a urethane prepolymer having an isocyanate group, and a curing agent. At least one of the base and the curing agent contains polymer particulates having an average particle size of from 0.01 to 200 μm, the polymer particulates having a glass transition temperature of from −40° C. to +80° C., a content of the polymer particulates is ≥5 mass % in a total amount of the adhesive composition. A cured product of the adhesive composition has a loss tangent of ≥0.15 under a temperature region of from −40° C. to +80° C. and a frequency of 100 Hz, and the cured product not breaking under a stress amplitude of 2.8 MPa and a repetition number of up to 10times in a tensile shear fatigue property test JIS K6864.
