A molded body includes a non-foamed design layer, a foamed intermediate layer, and a non-foamed back layer, laminated in this order and formed of a first, second, and third resin compositions, respectively. The first, second, and third resin compositions contain a polyolefin as a main component. The first resin composition is an impact-resistant resin composition including a polyolefin, a polyamide, and a polyolefin-based modified elastomer having a reactive group reactive with the polyamide. A method of producing the molded body includes disposing a first support layer to serve as the design layer and a third support layer to serve as the back layer so as to be spaced apart from and face each other, interposing the second resin composition provided with foamability in a gap between the first and third support layers, and forming the intermediate layer by expanding the gap while causing the second resin composition to foam.
