A bowl-shaped container (10a) which is as a hermetically sealed container includes a bowl-shaped container (10a) having a space to contain contents (51) at the inside and an opening to take in and out the contents (51), and a lid (17) mainly made of plastic to seal the opening of the bowl-shaped container (10a), which is heat-sealed to a rim of the opening of the bowl-shaped container (10a). The bowl-shaped container (10a) adheres a coating film (12) mainly made of biodegradable plastic and having at least hydrophobicity to the surface of the main body (11a) of the container mainly made of starch. The main body (11a) is molded through steam expansion of a slurry or dough molding material containing starch and water. For these reasons, it is possible to provide a hermetically sealed container mainly made of starch having sufficient strength and at least sufficient water resistance, and a very excellent biodegradability.
