To provide a structural element which does not expose a passenger (and/or, crew) to a riskiness since kinetic energy of collision is not transmitted to a cabin at an accident (or collision or especially in collision at rear) by indicating a high flexible rigidity and bending strength though it has a low tare weight per unit area.
A sandwich-like element includes two outside layers coupled to (a) a core layer and (b) a core layer, (c) occasionally, at least one gluing layer located between the core layer and the outside layer, at least one stripping means at a first (extending) side of the sandwich-like element. The stripping means is disposed between the outside layer by the side of the first (extending) and the core layer, or the sandwich-like element contained 1/3 outside of the core layer by the side of the first (extending). Further, the sandwich-like element is applicable to an automobile field of such a sandwich-like element.
