Abstract
A biodegradable resin bottle having a container wall () including a biodegradable resin and having a vacuum-evaporated film () formed on the inner surface of the container wall () by a plasma CVD method. The vacuum-evaporated film () includes a first hydrocarbon vacuum-evaporated layer () positioned on the inner surface of the container wall and a second hydrocarbon vacuum-evaporated layer () formed on the above hydrocarbon vacuum-evaporated layer (). The first hydrocarbon vacuum-evaporated layer () has polar groups introduced therein. The second hydrocarbon vacuum-evaporated layer () exhibits hydrocarbon peaks stemming from CH, CHand CHin a region of wave numbers of 3200 to 2600 cmas measured by FT-IR, has a CHratio of not larger than 35% and a CHratio of not smaller than 40% per the sum of CH, CHand CHcalculated from the hydrocarbon peaks, and has no polar group introduced therein.
