Provided is a fluorescent zirconia material. When a frame (14) is fired at a high temperature of 1300-1600°C, a fluorescent property, i.e., an ability to generate fluorescence upon UV irradiation, is imparted to the frame (14) comprising zirconia, due to Eu 2 O 3 which is contained in the zirconia material constituting the frame (14). For example, when the cross section surface of the frame (14) is irradiated with a UV lamp, a black light or the like upon breakage, the frame generates fluorescence and thus shows traceability. When irradiated with a blank light, the frame (14) generates blue fluorescence and a thin part in an upper layer (18) and a part not provided therewith also have the same fluorescent property as the upper layer (18), which brings about an esthetical merit too.
