Abstract:
A low-cost magnetostrictive torque sensor having a high sensitivity is obtained. A torque sensor  10  includes a substrate  12,  a magnetostrictive portion  26,  a magnetostrictive portion  28,  a detection coil  18 a,  a detection coil  18 b,  a detection circuit  48,  and a detection circuit  50.  The substrate  12  has a tubular shape. Each of the magnetostrictive portions  26  and  28  is constituted by a plating film and disposed on the outer peripheral surface of the substrate  12.  The detection coil  18 a  generates a magnetic flux passing through the magnetostrictive portion  26.  The detection coil  18 b  generates a magnetic flux passing through the magnetostrictive portion  28.  Each of the detection circuits  48  and  50  detects a potential between the detection coil  18 a  and the detection coil  18 b.

Claim (Index 2):
The magnetostrictive torque sensor of  claim 1 , further comprising:\n a power supply that generates an alternating current and supplies a power supply voltage of one of a positive voltage or a negative voltage to the first coil and the second coil; and a potential generating circuit that generates an intermediate potential between a potential of the power supply voltage and a ground potential, wherein the power supply supplies the power supply voltage to the first coil and the second coil so that the alternating current flows in each of the first coil and the second coil, the potential generating circuit sets a potential at a midpoint between the first coil and the second coil at the intermediate potential, and the detection circuit detects a potential between the first coil and the midpoint and a potential between the second coil and the midpoint.
