Provided are a molded body, a method for manufacturing the same, and a method for recycling the same. A molded body (1) is provided with a non-foamed design layer (11), a foamed intermediate layer (12), and a non-foamed rear surface layer (13) laminated in this order, each layer being formed from a first resin composition, a second resin composition, and a third resin composition, each of which is mainly composed of a polyolefin. The first resin composition is an impact-resistant resin composition containing a polyolefin, a polyamide, and a polyolefin-based modified elastomer having a reactive group that reacts with the polyamide. This method for manufacturing a molded body is provided with: an arrangement step in which a first support layer, which is a design layer, and a third support layer, which is a back surface layer, are arranged so as to face each other while being separated from each other; a sandwiching step for sandwiching the second resin composition, which has been imparted with foamability, in t
