を特徴とする磁気センサ。[Claims for Utility Model Registration] A magnetic sensor in which magnetized patterns are arranged along a scale formed on the surface at predetermined intervals, and the relative movement of the scale is detected by changes in the magnetized direction of the scale. The sensor body includes a sensor body that detects the direction of a surrounding magnetic field, and a yoke made of a high magnetic permeability material, one end of which is disposed on the back surface of the sensor body, and the other end of which is disposed close to the scale surface. A magnetic sensor characterized by:
