To provide an evacuation map sign whose evacuation information is illuminated readably to be visible at night using light emission of a light accumulating material effectively.
This evacuation map sign 1 includes an optically transparent plate body 2, a printing layer 3 that is disposed on the back surface of the plate body and shows evacuation information 10 including an evacuation map, and a photoirradiation layer 4 containing the light accumulating material disposed on the back surface of the printing layer. Energy stored in the light accumulating material of the photoirradiation layer at daytime is emitted as light at night, the evacuation information of the printing layer appears visibly even in a dark place with the light from the light accumulating material, a sign person certainly visually recognizes the evacuation information and uses it for safe evacuation.
