PROBLEM TO BE SOLVED: To provide a plastic container of high gas barrier properties which cannot be obtained with a known plastic container having a barrier layer of a single-layered thin film mainly comprising a silicon compound. SOLUTION: The plastic container has a compound thin film of gas barrier properties consisting of a plurality of layers of thin films 2 of gas barrier properties deposited on an inner surface of the container by a plasma chemical vapor deposition method and mainly comprising silicon oxide in which the degree of oxidation of each layer is successively increased from the first layer to the uppermost layer.
