Beschreibung
Zusammenfassung:	A torque sensor includes: a strain body; and an optical sensor configured to detect a deformation of the strain body. The strain body includes an outer peripheral portion having a ring shape, and an inner peripheral portion of which at least a part is disposed inside the outer peripheral portion in a radial direction. The optical sensor includes a scale fixed to one of the outer peripheral portion and the inner peripheral portion, and disposed between the outer peripheral portion and the inner peripheral portion, and a detector fixed to a remaining one of the outer peripheral portion and the inner peripheral portion, and disposed to face the scale between the outer peripheral portion and the inner peripheral portion.
