PROBLEM TO BE SOLVED: To provide the process for manufacturing an expanded molding which forms ruggedness on the entire surface of the expanded molding and improves the aesthetic appearance without using a molding mold with a rugged pattern, and gives an expanded molding having least scratch-prone surfaces, an expanded molding molded by the process, and a luggage box for a vehicle composed of the expanded molding. SOLUTION: The process for manufacturing the expanded molding includes the expansion molding step to obtain a primary molding by in-molding expanding resin particles filling the molding space in the molding mold, and the ruggedness formation step to form ruggedness by re-expanding at least the surface of the primary molding by heating the primary molding taken out of the molding space.
