A bowl-shaped container () which is as a biodegradable molded article adheres a coating film () mainly made of biodegradable plastic and having at least hydrophobicity to the surface of the main body () of the container mainly made of starch. The main body () is molded through steam expansion of a slurry or dough molding material containing high-amylose starch and water, or a slurry or dough molding material containing starch, polyvinyl alcohol and water. For these reasons, it is possible to accomplish sufficient strength and at least sufficient water resistance, to exert a very excellent biodegradability and further to provide a biodegradable molded article having excellent moisture absorption strength mainly made of starch even if the biodegradable molded article has a complicated shape.
