[PROBLEMS] To provide a method for manufacturing a phosphorescent plate, which generates phosphorescence having sufficient luminance and has improved phosphorescence characteristics, and to provide the phosphorescent plate. [MEANS FOR SOLVING PROBLEMS] A method for manufacturing a phosphorescent plate (100) has a first dot forming step of forming a first dot by applying a first liquid mixture, which contains a glass frit, a phosphorescent material and a resin, in a dot shape on one surface of a substrate (10); a spray step of spraying the phosphorescent material on the surface of the first dot, drying the material and forming a first dot layer (21); a coating step of forming a coating layer (22) by coating the surface of the first dot layer (21) with a second liquid mixture containing a glass frit, a phosphorescent material and a resin; and a first burning step of forming a phosphorescent layer (20) by burning the first dot layer and the coating layer (22). |
