PROBLEM TO BE SOLVED: To improve the drainability and walking property as a floor structure by protrusively fixing a frame consisting of a plurality of joists to a building skeleton, laying a metallic folded plate member on the upper surface of the joists to form a floor bed part, and laying a plurality of unit floor decorative members on the floor bed part. SOLUTION: The rear beam member 4 of a frame is fixed to a building skeleton H, a folded plate-like member 20 is laid on a joist 8 to form a floor bed part, and a floor decorative member 30 is placed on the floor bed part. A corrugated form consisting of a valley part 21 and a mountain part 22 is continuously formed on the folded plate-like member 20. The valley part 21 of the folded plate-like member 20 is formed into a dovetail groove shape, and the dovetail groove-shaped valley part 21 and the mountain part 22 having a flat surface are repeatedly formed at a fixed pitch. The peripheries of the folded plate-like member 20 and the laid unit floor decorative member 30 are inserted to opening parts 10, 10 together with the joist 8 and fixed. According to this, excellent feeling of walking can be obtained, and the water flowing down can be drained in a short time.
