Provided herein is a self-etching dental adhesive that exhibits excellent adhesiveness not only to dentin untreated by phosphoric acid etching, but to dentin treated by phosphoric acid etching. The present invention relates to a dental adhesive containing a (meth)acrylamide compound (a), an asymmetric acrylamide-methacrylic acid ester compound (b), and an acid group-containing (meth)acrylic polymerizable monomer (c). The (meth)acrylamide compound (a) is at least one selected from the group consisting of compounds represented by general formula (1), and compounds represented by general formula (2). The asymmetric acrylamide-methacrylic acid ester compound (b) is a compound represented by general formula (3).
(In the formulae, the meanings of the symbols are omitted.)
