Abstract
To provide a magnetic encoder that is stable relative to an outside force and has only small variation of a gap between a magnetic sensor and a magnetic medium. The magnetic encoder includes a magnetic medium placed on a first member and a magnetic sensor placed on the second member, the first and second member for moving relative to each other. The magnetic sensor includes a sensor substrate, a sensor holding plate for holding the sensor substrate, and a wire for extracting a signal from the magneto-resistive element to outside. The sensor holding plate includes a fixing portion for fixing the sensor holding plate to the second member, a sensor holding member for holding the sensor substrate, and a plurality of arm portions provided in the relative movement direction with the sensor holding member in-between and extending from the fixing portion to constitute a cantilever.
