PROBLEM TO BE SOLVED: To provide a magnetic resistance type displacement sensor whose output does not change even if it is used in an environement where a temperature gradient may be generated in the magnetic resistance type displacement sensor itself. SOLUTION: In a magnetic resistance type displacement sensor 1 having a base board 10 on which magnetic resistance elements are arranged and a bias magnet 4 to apply magnetic field to this base board 10, first and second magnetic resistance elements 2 and 3 having the same configuration are arranged on the same base board 10, and a short-circuit electrode is only arranged on the first magnetic resistance element 2 among these, and a bridge circuit using an electric potential difference between these output as output is composed of the two magnetic resistance elements 2 and 3. |
