【Task】 Biodegradable foam with excellent biodegradability, moldability, and heat resistance, and highly safe even when used for food packaging containers, its production method, and biodegradability using the foam To provide a molded product and a manufacturing method thereof. [Solution] It is a biodegradable foam obtained by mixing starch, a biodegradable thermoplastic resin and an inorganic filler, and foamed with a foaming ratio of 15 times or less. Preferably, the starch contains 5 to 40% by weight and the inorganic filler contains 1 to 15% by weight. In addition, the biodegradable thermoplastic resin is preferably a mixture of two or more resin components having different melting points, and in particular, a low melting point resin is more extensible than a high melting point resin, More preferred.
