Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a communication apparatus capable of preventing malfunction in non-contact communication.SOLUTION: The communication apparatus includes: a non-contact communication section that performs non-contact communication with a non-contact communication medium via a loop antenna; and a display section. The number of polarity inversion times of a voltage which is applied to the display elements in the display section per unit time is set out of an influence rejoin where a carrier wave used for non-contact communication is influenced on modulation or demodulation. 【課題】非接触通信における誤動作を抑制できる通信装置を提供する。【解決手段】非接触通信媒体との間において、ループアンテナを介して非接触通信する非接触通信部と、表示部と、を備え、表示部の表示素子に印加される電圧の単位時間あたりの極性反転回数は、非接触通信に使用される搬送波の変調又は復調に対して影響を与える領域である影響領域外に設定される。【選択図】図３
