Abstract
A plastic formed article comprising a plastic substrate and a vapor deposited film formed on the surface of the plastic substrate by a plasma CVD method, wherein the vapor deposited film includes an organometal vapor deposited layer having an element ratio C/Si of 2.5 to 13 and an element ratio O/M of not larger than 0.5, and a hydrocarbon vapor deposited layer; and the hydrocarbon vapor deposited layer has a thickness in a range of 40 to 180 nm, exhibits peaks stemming from CH, CHand CHover a region of wave numbers of 3200 to 2600 cmas measured by FT-IR, and has a CHratio of not larger than 35% and a CHratio of not less than 40%. A film is deposited on a plastic formed article without deteriorated by oxidation, without thermally deformed or without thermally deteriorated not only when PET or polyolefin is used but also when polylactic acid is used as the plastic substrate.
