Disclosed is a person it is possible to pass through at the desired position without electric shock, to provide an electric fence which can check the voltage state easily. A conductive member which is formed around the predetermined area, with is conductive member and electrically connected to a first voltage generating circuit for applying a first voltage to the conductive member, the conductive member and the electrical and is connected to, is applied to the third conductive member a voltage having a voltage value lower than the first voltage when the second voltage is applied to the conductive member having a lower voltage value than the first voltage a third voltage generating circuit which, along with being removably and electrically connected to the conductive member, the first notification means that the first voltage is notified when it is connected to the conductive member is applied, the Electric fence comprising a second voltage generating means capable of generating a second voltage and a second voltage generating means announcement device and a second notification means for notifying if that caused the second voltage. [Selection Figure] Figure 1【課題】人が感電することなく所望の位置で通り抜けることができると共に、電圧状態を容易に確認できる電気柵を提供する。【解決手段】所定領域の周囲に形成された導電部材と、導電部材と電気的に接続されると共に、導電部材に第1の電圧を印加する第1の電圧発生回路と、導電部材と電気的に接続されると共に、第1の電圧よりも低い電圧値を有する第2の電圧が導電部材に印加された場合に第1の電圧よりも低い電圧値を有する第3の電圧を導電部材に印加する第3の電圧発生回路と、導電部材に着脱可能にかつ電気的に接続されると共に、第1の電圧が印加された導電部材に接続された場合に告知する第1の告知手段と、第2の電圧を発生可能な第2の電圧発生手段と、第2の電圧発生手段が第2の電圧を発生させた場合に告知する第2の告知手段とを有する告知器とを備える電気柵。【選択図】図1
