    • There is provided, in a simple manner, a synthetic resin container which improves a vapor barrier property while maintaining a gas barrier property against oxygen or the like at a high level. The present invention is a PET bottle having a barrier film 2 formed on an inner surface of a wall portion 1 constituting a container body made of PET resin by a plasma CVD method with organic silicon compound gas and oxygen gas as raw materials, the barrier film containing silicon oxide in which a compositional ratio of oxygen among silicon, oxygen and carbon is not less than 50 atom % and a compositional ratio of carbon among silicon, oxygen and carbon is not less than 3 atom % and not more than 20 atom %. Preferably, compositional ratio of carbon in the barrier film 2 is not more than 8 atom %.
    • 以简单的方式提供一种合成树脂容器,其在保持高氧气等的阻气性的同时提高了蒸气阻隔性。 本发明是一种PET瓶,其具有阻挡膜2,该阻挡膜2通过等离子体CVD法以有机硅化合物气体和氧气为原料形成在构成由PET树脂制成的容器主体的壁部1的内表面上,阻挡膜 其中硅,氧和碳之间的氧的组成比不小于50原子%,硅,氧和碳之间的碳的组成比不小于3原子%且不超过20原子%。 优选地,阻挡膜2中的碳的组成比不大于8原子%。
