PROBLEM TO BE SOLVED: To provide an unauthorized communication establishment prevention system and electronic key that are capable of more correctly performing correctness determination on IC collation communication.SOLUTION: An electronic key 2 comprises: an azimuth sensor 22 for detecting an azimuth to which the electronic key 2 turns; and a magnetic field variation generation unit 25 for varying a magnetic field applied to the azimuth sensor 22. The magnetic field variation generation unit 25 includes a frame 27 inside which liquid 26, a high specific gravity member 28, and a low specific gravity member 29 are stored. The magnetic field variation generation unit 25, even when the electronic key 2 has stopped after the electronic key's moving state, is capable of varying a magnetic line to be applied to the azimuth sensor 22 because the high specific gravity member 28 and a low specific gravity member 29 move in the liquid 26.SELECTED DRAWING: Figure 3

【課題】ＩＤ照合の通信の正否判定を、より正しく行うことができる通信不正成立防止システム及び電子キーを提供する。【解決手段】電子キー２は、電子キー２が向く方位を検出する方位センサ２２と、方位センサ２２に付与される磁場を変化させる磁場変化発生ユニット２５とを備える。磁場変化発生ユニット２５は、筐体２７の内部において、液体２６、高比重部材２８及び低比重部材２９が入っている。磁場変化発生ユニット２５は、電子キー２が動いた状態をとった後に停止しても、高比重部材２８及び低比重部材２９が液体２６内を動くことにより、方位センサ２２に付与される磁力線を変化させることが可能である。【選択図】図３
