Abstract

　機器間の通信を確実に行うことができ、しかも、機器配置の自由度が大きい通信システムを提供すること。送受信機（１）は、情報信号を電界に変換して送信する送信部、及び電界を受信して前記情報信号に変換する受信部を有する送受信回路（１１）と、伝送媒体（３）を介して電界信号を受ける個々の電極（１４ａ～１４ｅ）との間のスイッチ（１３）を切り替えるスイッチング回路（１２）と、スイッチング回路（１２）におけるスイッチ（１３）の切り替えを制御する制御回路（１５）とから主に構成されている。送受信機（２）は、情報信号を電界に変換して送信する送信部、及び電界を受信して前記情報信号に変換する受信部を有する送受信回路（２１）と、伝送媒体（３）を介して伝送された電界信号を受ける電極（２２ａ，２２ｂ）とから主に構成されている。
