The present invention provides a dental adhesive composition that, even after photocuring with a high-output LED irradiator, shows high bond strength not only for dentin untreated by phosphoric acid etching but also for dentin treated by phosphoric acid etching. The present invention relates to a dental adhesive composition comprising a phosphoric acid group-containing polymerizable monomer (A), the phosphoric acid group-containing polymerizable monomer (A) comprising: a dihydrogen phosphate monoester group-containing polymerizable monomer (A-1) represented by general formula (1); a hydrogen phosphate diester group-containing polymerizable monomer (A-2) represented by general formula (2); and a phosphoric acid tetraester group-containing polymerizable monomer (A-3) represented by general formula (3).
