A two-package dental adhesive composition is provided that has an excellent adhesive property for each of various dental materials and also has excellent storage stability. The two-package dental adhesive composition includes a first agent and a second agent which are divided from each other. The two-package dental adhesive composition includes at least five components including: (A) an acidic group-containing polymerizable monomer; (B) a sulfur atom-containing polymerizable monomer; (C) a silane coupling agent; (D) a borate compound; and (E) water. The first agent contains only (A) the acidic group-containing polymerizable monomer and (B) the sulfur atom-containing polymerizable monomer out of the five components. The second agent contains only (C) the silane coupling agent, (D) the borate compound, and (E) the water out of the five components.
