Abstract

Abstract A frame structure for a communication system includes a framework for accommodating a communication system and a cover member mounted on the framework. The cover member has an insulating material layer provided between a semiconducting material layer and a conducting material layer, and is mounted so that the conducting material layer will face inside. The semiconducting material layer and the conducting material layer are electrically connected to each other.
