PROBLEM TO BE SOLVED: To obtain a fluorescent article provided with a phosphorescent fluorescent material layer having a specific different kind of laminated phosphorescent fluorescent material layer, capable of holding the brightness of light from the lower layer and ensuring sufficient visibility over a long period, and capable of directly and easily forming the phosphorescent fluorescent material layer to a wall surface, a floor surface, etc. SOLUTION: A fluorescent article is provided with a phosphorescent fluorescent material layer comprising (A) the layer of a compound of formula: Me4 Al14 O25 :X (Me is strontium, magnesium, calcium; X is europium, cerium, lanthanum, terbium, dysprosium, thulium) as a lower layer and (B) the layer of a compound of formula: MeAl2 O4 :X as a surface layer. The surface layer preferably has a thickness of <=250μm.
