Reference numeral 10 is a biodegradable container body comprising a natural polysaccharide or protein, or a substance obtained by chemically modifying the polysaccharide or protein within the range of biodegradability. Is a hydrophobic biodegradable plastic thin film that covers the surface of the biodegradable container body 10. Examples of the natural polysaccharides used in the present invention include simple substances such as starch, cellulose, agarose and carrageenan, and examples of proteins include gelatin. Alternatively, a mixture of polysaccharide and protein may be used. Further, the foam of the above substance promotes the biodegradability rate, and is more preferable as the biodegradable raw material of the biodegradable container body 10 of the present invention. Examples of the hydrophobic biodegradable plastics include polycaprolactone, polyglycolide, poly (3-hydroxybutyrate), poly (3-hydroxybutyrate-co-3 hydroxyvalerate) and the like.
