SOLUTION: This double floor is equipped with a plurality of row of supporting leg structures L which are juxtaposed on a floor slab S, and a plurality of floor panels P which are laid between the adjacent structures L and L. Each of the structures L is equipped with a beam material 20 on which an end of each floor panel P is placed, and at least three post materials 10 which are interposed between the beam material 20 and the floor slab S.
