A one-pack type dental adhesive composition-that does not require a pre-treatment such as an etching treatment and a priming treatment and can surely adhere a dental restoration material to a tooth structure and keep an adhesive effect over a long period of time, comprised of a polymerizable composition containing (a) 1 ∼ 5 % by weight of a polymerizable monomer containing a phosphoric acid group, (b) 10 ∼ 40 % by weight of a polymerizable monomer containing a plurality of carboxyl groups in one molecule, or being readily reactive with water to generate a plurality of carboxyl groups in one molecule, (c) 20 ∼ 40 % by weight of an acid group-free polymerizable monomer or a mixture of two or more acid group-free polymerizable monomers, both having a solubility of water at 25 °C of 25 % by weight or less, and (d) 15 ∼ 50 % by weight of water, with (e) 0.1 ∼ 5.0 parts by weight, based on 100 parts by weight of the polymerizable composition, of a photo-polymerization initiator and (f) a viscosity modifier having a mean particle size of 0.01 ∼ 0.05 µm, the dental adhesive composition having a viscosity of 0.1 ∼ 1 Pa·s.
