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