PROBLEM TO BE SOLVED: To provide a floor structure for a balcony capable of being easily constructed on a building such as a housing having a balcony while reducing a level difference in water gradient on a floor surface on which a drainage ditch is provided. SOLUTION: A floor structure for a balcony has a drainage ditch 54 provided on a floor surface 52 of an inner balcony for collecting water flowing on the floor surface 52. The drainage ditch 54 is disposed almost in the middle between the outside end 52a and the inside base end 52b of the floor surface 52 of the balcony and a gradient is applied to the floor surface 52 so as to descend from the outside end 52a and the inside base end 52b toward the drainage ditch 54. In the drainage ditch, the length of the floor surface 52 in the gradient direction which is gradient from the drainage ditch 54 to the end 52a and the base end 52b of the floor surface 52 of the balcony is reduced, compared to a structure that the drainage ditch is provided at the end or the base end of the floor surface to which a water gradient is applied.
