Abstract

A polylactic acid formed body including a polylactic acid base material () and a hydrocarbon film () vapor-deposited on the surface of the base material by a plasma CVD method. The polylactic acid base material () exhibits a sharp X-ray diffraction peak in which a half-width of peak appearing in the 10°-25° wide angle X-ray measurement is not more than 1.22°, and the hydrocarbon film () is vapor-deposited on the surface of the polylactic acid base material (), and includes two layers of a high CHlayer () having a ratio of CHper the total of CH, CHand CHof not less than 40% and a low CHlayer () formed on the high CHlayer () and having a ratio of CHper the total of CH, CHand CHof not more than 35%.
