Abstract
A magnetostriction type torque sensor employs a plurality of detector coils arranged in axial arrangement along an objective rotary body. The detector coils are so designed and arranged as to compensate influence of temperature, particularly the error caused due to axial temperature gradient caused in the objective rotary body.
