Abstract
A multilayered structure having a liquid layer () on a surface of a plastic underlying layer (), wherein a liquid diffusion prevention layer () is provided on the lower side of the underlying layer () to suppress or block a diffusion of a liquid that forms the liquid layer (), and a covering ratio F of the liquid layer () is maintained to be not less than 0.5. With this structure, the surface properties of the liquid layer () can be stably maintained over long periods of time.
