Summary:To improve the estimation accuracy of the position of a coil used as a marker in a magnetic measurement device.SOLUTION: A magnetic measuring device includes at least: one or more magnetic sensors; a coil; a drive unit that supplies electric current to the coil; a conducting wire connecting the coil and the drive unit; and a computing unit for estimating a relative position between the magnetic sensor and the coil on the basis of detection, by the magnetic sensor, of a magnetic field generated by the current supplied to the coil, where the magnetic sensor has sensitivity in a specific direction and the specific direction of the magnetic sensor is parallel to an electric current vector flowing through the conducting wire.SELECTED DRAWING: Figure 1 【課題】磁気計測装置においてマーカとして使用するコイルの位置の推定精度を向上する。【解決手段】磁気計測装置は、少なくとも１つ以上の磁気センサと、コイルと、前記コイルに電流を供給する駆動部と、前記コイルと前記駆動部とを接続する導線と、前記コイルに供給した電流により発生する磁場の前記磁気センサによる検出に基づき前記磁気センサと前記コイルとの相対位置を推定する演算部と、を有し、前記磁気センサは、特定方向に感度を有し、前記磁気センサの前記特定方向と、前記導線に流れる電流ベクトルとが平行であることを特徴とする。【選択図】 図１
