PROBLEM TO BE SOLVED: To provide a three-dimensional (3D) topographical map eliminating the necessity of sharply modifying or reforming the map or preparing a plurality of 3D topographical maps when contents necessary for the display of the map are changed or a plurality of contents intended to be displayed exist and capable of expressing a target to be dynamically changed. SOLUTION: The 3D topographical map is provided with a translucent film body three-dimensionally expressing contents necessary for the display of topography or the like on the surface and forming a light diffusion layer on the rear face, an image film drawing the contents necessary for the display on the back of the film body and a light source having an optical system for projecting the contents expressed on the image film to the rear face of the film body.
