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 1):
A magnetostrictive torque sensor comprising:\n a substrate having a columnar or tubular shape; a first magnetostrictive portion and a second magnetostrictive portion each disposed on an outer peripheral surface of the substrate and constituted by a plating film; a first coil that generates a magnetic flux passing through the first magnetostrictive portion; a second coil that generates a magnetic flux passing through the second magnetostrictive portion and is electrically connected to the first coil in series; a first resistor disposed between the first coil and the second coil and electrically connected to the first coil and the second coil in series; a second resistor disposed between the first resistor and the second coil and electrically connected to the first resistor and the second coil in series; and a detection circuit that detects a potential between the first coil and the first resistor and a potential between the second coil and the second resistor.
