This denture plate includes: a plate portion; a socket which is demarcated by means of a step portion with respect to a gingival part of the plate portion and into which an artificial tooth is fitted; and an interdental papilla part of the gingival part, located at both ends of the socket along the tooth row, and corresponding to an interdental papilla between adjacent teeth. In a state in which the socket is facing upward, a basal surface of the socket includes a socket top portion assuming a ridge shape linking the interdental papillaparts at both ends, and constitutes a convex surface as a whole. A border part of the basal surface abuts continuously against the step portion, and the socket top portion is positioned at substantially the same height as or
