An anti-chipping sheet includes at least a substrate layer and a pressure-sensitive adhesive layer, wherein the substrate layer comprises laminated multiple ionomer layers, each of which comprises an ionomer produced by neutralizing carboxyl groups of an ethylene-unsaturated carboxylic acid copolymer with metal ions, one of the multiple ionomer layers is a high-rigidity ionomer layer, located at the outermost layer and not in contact with the pressure-sensitive adhesive layer of the substrate layer, and having stiffness of 200 N/mm2 or higher, and another one of the multiple ionomer layers is a low-rigidity ionomer layer, located toward the pressure-sensitive adhesive layer in relation to the outermost layer, and having stiffness of lower than 200 N/mm2. |
