PROBLEM TO BE SOLVED: To provide a floor structure excelling in floor impact sound cut-off performance and improving workability. SOLUTION: An upper floor material 14 is supported on a deck plate 32, and elastic members 42 of dynamic vibration absorbers 36 are supported to the deck plate 32 through mounting bolts 40 or the like. Consequently, when vibration is applied to the upper floor material 14, this vibration is transmitted to the elastic members 42 of the dynamic vibration absorbers 36 through the deck plate 32. The elastic members 42 of the dynamic vibration absorbers 36 are thereby deformed elastically, and mass bodies 44 supported by the elastic members 42 in the dynamic vibration absorbers 36 are vertically moved to absorb the vibration to thereby damp the vibration from the upper floor material 14 to a floor slab 12.
