An encoder includes a magnetic sensor having higher detection sensitivity to a magnetic field applied in a reading direction, while having lower detection sensitivity to a magnetic field applied in a direction forming a greater angle with respect to the reading direction, an encoder substrate having the magnetic sensor mounted thereon, a magnetic shield to shield against a magnetic field including a side portion covering sides of the magnetic sensor and a top-side portion covering a top of the magnetic sensor, a permanent magnet located to face the encoder substrate, a shaft having the permanent magnet attached to a tip end of the shaft, and a bracket to support the shaft in a rotatable manner, wherein on the side portion of the magnetic shield, a notch as a connector insertion portion is located not to overlap an extended area of the magnetic sensor in the reading direction.
