Abstract

A foam molded body having a rebound resilience coefficient equivalent to that of a petroleum-derived polyamide-based elastomer foam molded body, and excellent moldability during in-mold foaming; foam particles; and a method for producing the foam molded body. A polyamide-based elastomer foam molded body comprising 50 to 100 mass % of a block copolymer resin containing a polyamide block as a hard segment and a polyether block as a soft segment, wherein the copolymer resin has a biobased product content as measured by ASTM D6866 of 30% or more.
