There are provided a two-component curable composition exhibiting the same curability and the like as usual even when the equivalent ratio of a reactive group of a second agent to a reactive group first agent is lower than usual, and a two-component adhesive, a two-component coating agent, and a laminate which use the two-component curable composition. The two-component curable composition contains a first agent which is produced by reacting a monomer for introducing a branch unit into a molecule with a monomer for introducing a first functional group into a molecular terminal; and a second agent which has a second functional group reactable with the first functional group, wherein the branching coefficient of the first agent is 1/f or more (f is the number of functional groups possessed by a monomer having the largest number of functional groups among monomers for introducing a branch unit into a molecule); and the agents are mixed and used at such a ratio that the equivalent ratio of the second functional group to the first functional group is excessive for the number of first functional groups.
