PROBLEM TO BE SOLVED: To enable refuge guide without depending upon a light source by molding a transparent resin impregnated with a specific amount of a light storage material to form a sign plate which instructs the direction and place of refuge and fitting and fixing the sign at the time of emergency plate to an opaque colored resin plate to exhibit fluorescent color in the dark. SOLUTION: The arrow indicating the direction and place of the refuge is molded at the sign plate 1 by molding the transparent resin into which the light storage material is incorporated. The sign plate 1 is fitted and fixed to the opaque colored resin plate of a square shape in external shape, by which the refuge guide sign S is obtained. The sign plate 1 is obtained by mixing the light storage material into the transparent resin, then molding the mixture to a desired shape. The main transparent resin constituting the sign plate 1 is more specifically an ABS resin, AS resin, acrylic resin, styrol resin, etc. The light storage material accumulates light energy and emits light by itself even after external light is removed and is more specifically, G-300M Green (particulate powder of 10μm in diameter) in N noctilucence (R).
