Abstract: The present invention provides a two-component type urethane-based adhesive composition for an automobile, which has a good productivity because of high curing rate, which there is not much change between physical properties of a cured product formed from a first component alone and those of a cured product formed from a mixture of first and second components, and which it is possible to satisfy required performances for an automotive adhesive without the second component. The present invention relates to a two-component type urethane-based adhesive composition for an automobile comprising (1) a first component comprising an isocyanate group-terminated polyether polyol compound, and (2) a second component comprising a polyol compound and curing catalyst, wherein a cured product from the first component alone has an elastic modulus of 5 to 20 MPa and an elongation of 300 to 850%, and wherein a cured product from a mixture of the first and second components at a mixing ratio of the first component to the second component of 100/10 has an elastic modulus of 3 to 20 MPa and an elongation of 300 to 650%.
