A sheet-like sandwich molding having two outer firm rigid covering layers and, as the core, at least one sheet-like structure of fiber material, which has been deformed by deep-drawing and been provided with synthetic resin. The sheet-like structure of fiber material, constituting the core, can, for example, be a knitted fabric provided with a curable condensation resin.
