<p>PROBLEM TO BE SOLVED: To provide a magnetic field rotation detection sensor capable of suppressing error in a detected angle, and a magnetic encoder thereof.SOLUTION: A magnetic field rotation detection sensor 20 detects rotation of a magnet, and includes a plurality of magnetic sensor elements 24a to 24d constituting a first bridge circuit 31, and a plurality of second magnetic sensor elements 25a to 25d constituting a second bridge circuit 32. A sensing axis 27 of the plurality of first magnetic sensor elements 24a to 24d and the sensing axis 27 of the plurality of second magnetic sensor elements 25a to 25d are directed in mutually perpendicular directions, and the plurality of first magnetic sensor elements 24a to 24d are arranged inner than the plurality of second magnetic sensor elements 25a to 25d.</p> |
