Description
境界面を挟んで隣接して一方向側と該一方向とは逆の他方向側とに分かれて配置された導電率の異なる2つの導体のみからなる本体部と、電圧を計測可能な電圧計を含む計測器とを有し、
前記一方側の導体には、該導体と同材料の端部が1つまたは複数形成されており、
前記他方側の導体には、該導体と同材料の端部が1つまたは複数形成されており、
前記一方向側の導体の端部及び前記他方向側の導体の端部のうちのいずれか2つの端部が、被測定回路に接続されて計測するべき被測定電流がそれらの間を流れる2つの入出力接続部であり、該2つの端部を含む前記一方向側の導体の端部及び前記他方向側の導体の端部のうちのいずれか2つの端部が、前記計測器が接続されて該2つの端部間の電位差を検出するための2つの検出接続部であり、
前記2つの入出力接続部間の抵抗は、前記計測器の入力インピーダンスよりも小さく、前記計測器によって前記2つの検出接続部間の電圧が計測可能となっており、該電圧が前記被測定電流と比例関係を持つ、ことを特徴とする。
