ABSTRACT:
A magnetostrictive torque sensor that detects a torque of a rotating shaft and/or a stationary shaft by using a magnetostriction inverse effect that occurs on a shaft surface, the magnetostrictive torque sensor includes a first detection coil, a second detection coil, a first oscillation circuit, a second oscillation circuit, a first direction magnetic permeability detector, a second direction magnetic permeability detector, and a torque detector.
