A load floor for a vehicle, by which, as the load floor is manufactured by including manufacturing a honeycomb structure with paper and adding polyurethane sheets to both side surfaces of the honeycomb structure, light and sufficient structural stiffness and a sound absorption effect are obtained through the honeycomb structure. As the polyurethane sheets are respectively provided on both surfaces of the honeycomb structure, sound absorption and insulation performances are obtained to further increase a sound absorption and insulation effect.
