いという欠点があつた。In order to prevent such troubles, a conductive material has been used as a packaging material or housing for these elements and parts. For example, there is a method in which a conductive powder is kneaded or applied to a plastic film. However, in the case of a general-purpose thermoplastic plastic film, it cannot be said that it is sufficient in terms of heat resistance and chemical resistance, and its use conditions are limited. A method of directly making a film from a conductive polymer has also been proposed, but since the electric conductivity changes relatively greatly due to changes in humidity, the conductive performance decreases, especially in an environment of low humidity, and as a result electrostatic discharge There is a drawback that the prevention effect is small.
