Abstract

A biodegradable laminate includes: an aliphatic polyester-based resin layer; a bonding layer; and a polyvinyl alcohol-based resin layer laminated on at least one surface of the aliphatic polyester-based resin layer with the bonding layer therebetween. The aliphatic polyester-based resin layer includes an aliphatic polyester-based resin composition containing an aliphatic polyester-based resin (A) including a repeating unit derived from an aliphatic diol and a repeating unit derived from an aliphatic dicarboxylic acid as main constituent units, a polyhydroxyalkanoate (B) including a 3-hydroxybutyrate unit as a main constituent unit, and an inorganic filler (C).
