A vehicle floor panel is provided in which a honeycomb core made of metal sandwiched and adhered between two CFRP plates is one in which a large number of core units formed into a polygon shape are continuous within one plane so as to share a side of the polygon. Since closed-section parts formed by a hat-shaped cross section part formed along the side and one CFRP plate are continuous with each other at a vertex of the polygon of the adjacent core units, not only is it possible to lighten the weight by opening the interior of the polygon (P) shape core unit, but it is also possible to enhance the energy-absorbing performance by dispersing and transmitting a collision load inputted into one direction of the floor panel toward a plurality of other directions because the high strength load transmission path is continuous with other load transmission paths.
