Abstract: To provide one liquid type dental adhesive composition that exhibits excellent adhesive property to glass ceramics, oxide-base ceramics and tooth substance, and has excellent storage stability, which are contrary features. One liquid type dental adhesive composition contains (a) silane coupling agent represented by general formula (1), (b) acidic group-containing polymerizable monomer, (c) volatile organic solvent, and (d) water. (In the formula, R1 represents an organic group having at least one functional group selected from the group consisting of a (meth)acryloyl group, a vinyl group and an epoxy group, R2 represents C4-C8 linear alkyl group, R3 represents C1-C8 alkyl group, and n is integer selected from 1 to 3.)
