Zusammenfassung:	An encoder includes a rotating body that is rotatable around a rotation axis; a disk that is fixed to the rotating body and has a scale formed in a ring shape; an optical module that is disposed to face the disk and detects the scale; a first magnet that is disposed on one side from the disk in a direction of the rotation axis and fixed to the rotating body; and a first magnetic detector that is disposed on a remaining side from the disk in the direction of the rotation axis and detects magnetism of the first magnet.
