Resin-made floor panel structure

The resin-made floor panel structure including a trunk floor (F) made of resin, and a trunk board (B) made of resin disposed so as to cover the trunk floor, a foamed layer having foams exposed at least in part is provided only on the side of the trunk board facing the floor panel. Thereby, in using resin materials for a floor panel, transmission of noise in the floor to the compartment side can be suppressed by a relatively simple structure without increasing the weight.
