To minimize noise in a compartment of an electric vehicle.SOLUTION: A vehicle floor structure includes: a linear projection 11 forming a floor tunnel 13 whose lower internal space communicates with a front compartment 70 at a front side of a vehicle on a convex groove-like section extending in a vehicular fore-and-aft direction at a center in a vehicle width direction; and flat plates 12L and 12R on both sides in the vehicle width direction of the linear projection 11. Further, the vehicle floor structure includes: a floor panel 10 forming a floor of a compartment 60; and a noise insulation plate 30 disposed at the front side of the vehicle of the floor tunnel 13 and partitioning the floor tunnel 13 in the vehicular fore-and-aft direction.SELECTED DRAWING: Figure 2
