A shielding component, in particular a heat shield, includes shield components (10, 12, 14) made flat, lying at least partially on top of one another, and connected to one another at least partially along at least one common connecting line (16). Since the shield components (10, 12) at least partially form a gasket (30) by at least one shield component (10) having a projection relative to its remaining superficial extent, a further function in the form of a sealing function is implemented in a heat shield for acoustic and heat insulation.
