An optical encoder includes a light emitting part for emitting light, a stationary slit part and a rotational slit part which allow part of the light emitted from the light emitting part to pass therethrough, a light receiving part for detecting the light passing through the stationary slit part and the rotational slit part, and a support for supporting the stationary slit part. The stationary slit part incudes a patterned portion in which a plurality of slits for allowing light to pass therethrough are formed, a fixed portion fixed to the support, and an elastic structure which is elastically deformable and provided between the patterned portion and the fixed portion. |
