Abstract

An object is to provide a lower vehicle-body structure of a vehicle capable of improving the proof stress of a rear end portion of a front floor panel against a side collision and avoiding the interference between a cross member of a kick-up portion and a battery unit. The lower vehicle-body structure of a vehicle includes: a first cross member 6 disposed on an intermediate portion of a front floor panel 1 in a vehicle front-rear direction so as to serve as a bridge in a vehicle width direction; a second cross member 40 disposed in a kick-up portion 10 between the front floor panel 1 and a rear floor panel 12 so as to serve as a bridge in the vehicle width direction at a position in which at least a center portion in the vehicle width direction is higher than the first cross member 6; and a battery unit disposed below at least the front floor panel 1 to a rear end position of the front floor panel 1, wherein a high-strength portion 70 for the front floor panel 1 is formed on a rear end of the front floor panel 1 on a lower end portion of the kick-up portion 10, the high-strength portion 70 being coupled to both of a pair of left and right side sills 2.
