A bumper of synthetic resin for use in an automobile includes a core, and an outer layer covering the core. The material for forming the core includes a main component produced by pulverizing a recovered bumper which has been formed using a polyolefine-based resin composition modified by an olefinic elastomer and which has a thermosetting synthetic resin coating film on its surface, and a polyethylene added to the main component. The material for forming the outer layer includes the polyolefin-based resin composition modified by the olefinic elastomer and the polyethylene in a content A2 which is smaller than a content A1 of the polyethylene in the core forming material (A2 < A1). The impact resistance of the core is enhanced with the addition of the polyethylene, despite the inclusion of the coating film particles. The outer layer is excellent in heat resisting characteristic, because of a smaller content of the polyethylene.
