Abstract: The present invention provides a dental adhesive exhibiting excellent initial bond strength and bond durability to both enamel and dentin. The present invention relates to a dental adhesive containing: an asymmetric acrylamide-methacrylic acid ester compound (a); an acid group-containing (meth)acrylic polymerizable monomer (b); and a water-soluble polymerizable monomer (c). The asymmetric acrylamide-methacrylic acid ester compound (a) is represented by the following general formula (1): where X is an optionally substituted, linear or branched C1 to C6 aliphatic group or an optionally substituted aromatic group, the aliphatic group is optionally interrupted by at least one linking group selected from the group consisting of —O—, —S—, —CO—, —CO—O—, —O—CO—, —NR1—, —CO—NR1—, —NR1—CO—, —CO—O—NR1—, —O—CO—NR1—, and —NR1—CO—NR1—, and R1 is a hydrogen atom or an optionally substituted, linear or branched C1 to C6 aliphatic group.
