Patent ID: 8133562

Claim:
A plastic formed article comprising a plastic substrate and a vapor deposited film formed on a surface of said plastic substrate by a plasma CVD method, wherein: said vapor deposited film includes an organometal vapor deposited layer formed on a side of said plastic substrate and having an element ratio C/M (M is a metal element) of 2.5 to 13 and an element ratio O/M of not larger than 0.5, and a hydrocarbon vapor deposited layer formed on said organometal vapor deposited layer; and said hydrocarbon vapor deposited layer has a thickness in a range of 40 to 180 nm, exhibits peaks stemming from CH, CH 2 and CH 3 over a region of wave numbers of 3200 to 2600 cm −1 as measured by FT-IR, and has a CH 2 ratio of not larger than 35% and a CH 3 ratio of not less than 40% per the total of CH, CH 2 and CH 3 calculated from the above peaks.
