It is intended to provide a biodegradable polyester resin composition which is excellent in gas barrier properties, mechanical strength and heat resistance and has Theological characteristics advantageously usable in molding a foamed article, etc., a process for producing the same, and a foamed article and a molded article using the same. The biodegradable polyester resin composition contains 100 parts by mass of a biodegradable polyester resin containing 59% mole or more of a hydroxycarboxylic acid unit, 0.01 to 10 parts by mass of a (meth)acrylic acid ester compound and 0.05 to 20 parts by mass of a layered silicate.

A biodegradable resin composition and an object molded or formed from the composition. The resin composition comprises: 100 parts by weight of a biodegradable polyester resin comprising not smaller than 50% by weight of polylactic acid having a melting point of not lower than 160&#xb0; C., the biodegradable polyester resin having a melt flow rate of 0.1 to 50 g/10 min as measured under a load of 21.2 N at 190&#xb0; C.; and 0.1 to 20 parts by weight of a phyllosilicate containing a primary, secondary or tertiary amine salt, a quaternary ammonium salt or a phosphonium salt ionically bonded between layers thereof.
