To suppress power consumption of a battery until a radio communication operation is executed.SOLUTION: The communication device includes: a substrate; a RF circuit driven by electric power supplied from a power supply section and mounted on the substrate; and a conductor part movable relatively to the substrate and constituting at least a part of an antenna. By moving at least part of the conductor part relatively to the substrate, a first state is obtained, in which the conductor part and a RF signal output terminal of the RF circuit are electrically connected and an electrode pattern on the substrate and the power supply section are electrically connected, and the power supply section and a power supply input terminal of the RF circuit electrically connected through the conductor part.SELECTED DRAWING: Figure 1 【課題】無線通信動作を行うまで電池の電力消費を抑える。【解決手段】基板と、電源部から供給される電力によって駆動され、基板に設けられるＲＦ回路と、基板に対して相対的に移動可能であり、アンテナの少なくとも一部を構成する導体部と、を備え、導体部の少なくとも一部が基板に対して相対的に移動することにより、導体部とＲＦ回路のＲＦ信号出力端子とが電気的に接続され、かつ、基板上の電極パターンと電源部とが電気的に接続され、かつ、電源部とＲＦ回路の電源入力端子とが導体部を介して電気的に接続される第１状態になる通信デバイス。【選択図】図１
