To provide a dental abutment having an embedded part embedded into an embedding hole of a block and fixed in the embedding hole. An uniform gap for a dental adhesive can be formed along an approximately entire circumference between an outer peripheral surface of the embedded part and an inner surface of the embedding hole. The dental abutment includes a gingiva contact part 1 having a forward-thicker truncated conical shape on the intraoral side a fitting part 2 projecting toward the jawbone side from the jawbone-side contact surface 1a of the gingiva contact part 1, and fitted into an end part on the intraoral side of the implant fixture so as not to rotate and an embedded part 3 to be embedded. Three or more projecting line parts 5 are formed on an outer peripheral surface 3a of the embedded part 3 so as to form the uniform gap.
