A plurality of drain holes are formed in the floor panel 1 by cutting with a cutter 18 in the vehicle width direction, for example, in a region where water drain holes are formed.
A cut 15 of 0 mm is formed. Next, a slit 11 extending in the vehicle width direction on a vertical plane by displacing the vehicle front side of the cut 15 downward with respect to the vehicle rear side with a horseshoe-shaped press die 19 having a bottom surface 19a having a downward slope 19a toward the vehicle rear side. At the same time, a water collecting area 10 having a downward slope toward the rear of the vehicle is formed on the vehicle front side of the cut 15.
