The present invention provides a magnetic linear encoder capable of enhancing the magnetization accuracy of a permanent magnet of a magnetic scale. More specifically, a magnetic linear encoder 100 has a magnetic scale 9 provided with a permanent magnet 96, and a magnetic sensor device 1 for detecting the magnetic field from the magnetic scale 9, and the magnetic sensor device 1 and magnetic scale 9 move relative to each other in a state of not being in contact with each other. The permanent magnet 96 comprises a magnetic coating layer 97 that includes magnetic powder and resin and is formed on one surface of a metallic base plate 95. The magnetic powder used in the permanent magnet 96 is a vertically oriented ferritic magnetic powder. The surface 960 of the permanent magnet 96 on the side of the magnetic sensor device 1 is in an exposed state. |
