[Problem] To provide a foamed blow-molded article that uses a polyethylene foamed resin and that is lightweight and has superior quality at a low cost. [Solution] The foamed blow-molded article is formed by means of foamed blow-molding of a resin material containing a polyethylene resin. The foamed resin contains an antioxidant and the total content of the antioxidant is at least 300 ppm. The antioxidant preferably results from the concomitant use of a phosphorus-based antioxidant and a phenol-based antioxidant, and the optimal content thereof is 250-3000 ppm of the phosphorus-based antioxidant and 250-750 ppm of the phenol-based antioxidant. During production, a resin to which at least 300 ppm of the antioxidant has been added and a recovered resin material are melted and mixed, a foaming agent is admixed, resulting in a foamed resin, and the foamed resin is blow-molded. |
