Summary:To increase the sensitivity of a magnetic sensor using a magnetic impedance effect.SOLUTION: A magnetic sensor includes: a non-magnetic substrate; a receiving element on the substrate, the receiving element including a soft magnetic body and having a longer direction and a shorter direction and also having the uniaxial magnetic anisotropy in a direction that intersects with the longer direction, the sensitive element receiving a magnetic field by the magnetic impedance effect; and a protrusion unit including a soft magnetic body, the protrusion unit protruding from an end of the receiving element in the longer direction.SELECTED DRAWING: Figure 1 【課題】磁気インピーダンス効果を用いた磁気センサの感度を向上させる。【解決手段】磁気センサは、非磁性の基板と、前記基板上に設けられ、軟磁性体を含み、長手方向と短手方向とを有し、当該長手方向と交差する方向に一軸磁気異方性を有し、磁気インピーダンス効果により磁界を感受する感受素子と、軟磁性体を含み、前記感受素子の前記長手方向の端部から突出する突出部とを備えることを特徴とする。【選択図】図１
