PROBLEM TO BE SOLVED: To provide a sandwich panel which is excellent in flame retardance while being reduced in weight, to provide a method of manufacturing the sandwich panel, and to provide an elevator car using the sandwich panel. SOLUTION: In the sandwich panel SP, a carbon fiber composite material layer 3a is attached to one side surface of a first foamed material layer 1 as a core material, and metal foil or a metal plate 4a is attached to the surface of the carbon fiber composite material layer 3a. A carbon fiber composite material layer is attached to the other side surface of the first foamed material layer 1, and metal foil or a metal plate 4b is attached to the surface of the carbon fiber composite material layer. A coating layer 5a is applied on the surface of the metal foil or the metal plate 4b, and a coating layer 5b is applied on the surface of the metal foil or the metal plate 4b.
