Summary:To provide a communication terminal capable of reliably performing short-range communication and electric field communication.SOLUTION: A communication terminal 1 used together with an IC card 20 including a loop antenna includes an electric field communication unit 12 that communicates with an authentication device 30 via a transmittable user P by an electric signal by a potential difference between a circuit unit 3 including a circuit pattern and a signal electrode 6. The circuit unit 3 is disposed in parallel with the signal electrode 6, and the signal electrode 6 has a gap portion 7 formed from an end.SELECTED DRAWING: Figure 1 【課題】近距離通信と電界通信とを確実に実行することができる通信端末を提供する。【解決手段】ループアンテナを有するＩＣカード２０と共に使用される通信端末１は、回路パターンを有する回路部３と、信号電極６との間の電位差による電気信号によって、伝達可能な利用者Ｐを介して認証装置３０と通信を行う電界通信部１２とを備え、回路部３と、信号電極６とは、平行に配置され、信号電極６には、端部から隙間部７が形成される。【選択図】図１
