Abstract
A method of manufacturing a heat resisting magnetic scale is disclosed which comprises a manufacturing process in which at least a part of a heat resisting base is heated and immediately cooled for the purpose of fusing the heated part to the base and changing both the magnetic characteristics of the part of the base which has been heated and the Curie point of the part which has been heated is raised to 100.degree. C. or higher.
