Abstract
There are provided plastic optical components which, in addition to their superior characteristics such as lightweightness, low cost and suitability for mass production, exhibit superior moisture barrier properties while experiencing extremely small changes in refractive index or other optical performance even if they are subjected to the effect of water in the environment; and an optical unit using such plastic optical components. The plastic optical component includes an optical component's body and an inorganic moisture-proof coating which is directly or indirectly formed by a plasma CVD process at least on surfaces of the optical component's body that contact outside air, and the plastic optical component is kept at a temperature of 80° C. or lower when the inorganic moisture-proof coating is formed by the plasma CVD process.
