PROBLEM TO BE SOLVED: To provide a molded article having an optional three-dimensional form and emitting accumulated light from whole of the article, to provide the molded material requiring no coking treatment by reinforcing waterproofness of the molded article itself, and to provide a general grade light-accumulating pigment which can achieve light-accumulating signs for escape and induction, which can be achieved only by using a specific grade light-accumulating pigment excellent in afterglow characteristic. SOLUTION: The molding material composition of the light-accumulating ceramics is prepared by blending 5 to 60 pts.mass aqueous dispersion obtained by dispersing by combining the oxide of at least one element among elements belonging to the third long period and the oxide of at least one element among elements belonging to a second short period in water, an alcohol or a mixed liquid of water and the alcohol based on 100 pts.wt. mixture obtained by blending by a ratio of 1 to 4 pts.mass powdery or granular light-accumulating pigment, 0.5 to 3 pts.mass glass frit and 4 to 8 pts.mass glass beads.
