An encoder includes an optical scale that has a phase difference plate, a light source section that irradiates the phase difference plate with light, and a light receiving section that receives the light from the phase difference plate, and outputs a signal corresponding to a received light intensity. The light emitted from the light source section is linearly polarized, and the light receiving section outputs a signal corresponding to a polarization state of the light from the phase difference plate.
