Provided is a bonding composition which, not requiring any pre-treatment such as acid-etching treatment or priming treatment, exhibits high initial bonding strength and good bonding durability. It comprises a mixture of an acid group-having polymerizable compound, a water-soluble film-forming agent, water, and a curing agent, in which the calcium salt of the acid is insoluble in water, and the film-forming agent is a polymerizable compound and is miscible with a physiological saline solution.
