PROBLEM TO BE SOLVED: To provide a double floor structure simple in construction and superior in thermal insulation performance, while firmly and stably connecting mutual adjacent floor panels. SOLUTION: This double floor structure is formed by firmly connecting and juxtaposing the mutual floor panels 5A to 5E via a connecting plate material 62, while supporting these floor panels 5A to 5E in a predetermined height position by support legs 2 to 4, by using a plurality of floor panels 5A to 5E formed by integrally installing a floor backing plate 60, thermal insulation materials 61A to 61E and the connecting plate material 62.
