PROBLEM TO BE SOLVED: To provide a luminous type evacuation guidance sign which is interchangeable with a conventional internal illumination type sign and prevents an evacuation guidance function from being lost in at least 20 minutes since power failure. SOLUTION: This luminous type evacuation guidance sign includes a luminous sheet; a light source part installed at one side face of the luminous sheet; and a sign part installed at the other side face side of the luminous sheet. The sign part is illuminated with the rays of light from the light source part through the luminous sheet, so that it is possible to recognize the sign, and to recognize the sign of the sign part with the rays of light to be emitted from the luminous sheet after the rays of light from the light source part disappear.
