Claim:
1. An aliphatic polyester resin composition comprising: a polyhydroxyalkanoate (A), an ethylene-vinyl acetate copolymer resin (B), and pentaerythritol (C), wherein the polyhydroxyalkanoate (A) is one or more selected from poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), and poly(3-hydroxybutyrate-co-4-hydroxybutyrate), the ethylene-vinyl acetate copolymer resin (B) has a vinyl acetate content of 65 to 95 wt %, and the polyhydroxyalkanoate (A) and the ethylene-vinyl acetate copolymer resin (B) are compatible and present in a weight ratio, (A)/(B) of 80/20 to 55/45, and wherein the ratio of 3-hydroxybutyrate/comonomer in said poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate), poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) is 97/3 to 80/20 mol %/mol %.
