A dental molded article has a predetermined shape so as to be used in an oral cavity, and contains polycaprolactone, acrylic resin, powdery silica, ascorbic acid, titanium oxide, a pigment, and zinc stearate. The acrylic resin is set to have a weight ratio of 5 to 30%, the powdery silica is set to have a weight ratio of 5 to 25%, the ascorbic acid is set to have a weight ratio of 0.3 to 1.8%, the titanium oxide is set to have a weight ratio of 0.001 to 0.02%, the pigment is set to have a weight ratio of 0.001 to 0.1%, and the zinc stearate is set to have a weight ratio of 0.001 to 0.1%, with respect to the polycaprolactone. Thus, a dental molded article and a dental resin material that can easily fit a mucosal surface in an oral cavity of a patient, are provided.
