ABSTRACT:
A magnetic encoder has a wiring structure which includes a retaining member 20 for retaining the magneto-sensitive element 37 in a certain positional relationship with respect to a surface on which a magnetic code is formed. This retaining member 20 is equipped with: a pair of gripping members 21c protruding toward the surface on which the magnetic code is formed; and an abutting member 21a adapted to abut against the back surface of the magneto-sensitive element 37 so as to keep the element 37 a certain distance apart from the surface on which the magnetic code is formed. The magneto-sensitive element 37, which is positioned by the abutting member 21a and the gripping members 21c, is fixed to the retaining member 20 by means of an adhesive agent or the like. The wiring structure may also include a protecting section 22, which is integrally formed with the retaining member 20 and which separates wiring member 35, or wiring member 50 for external electrical connection from a cover 40 of the encoder, thus preventing it from coming into contact with the cover 40.
