Claim Text:
1. A torque detecting device comprising: a permanent magnet that is a multi-polar magnet with a cylindrical shape in which magnetic poles are disposed in a circumferential direction; a magnetic yoke that is formed of a magnetic material and is disposed around the permanent magnet at a position in a magnetic field formed by the permanent magnet, and that rotates with respect to the permanent magnet so that a relative phase of the magnetic yoke with respect to the permanent magnet changes; a magnetic element that is disposed around the magnetic yoke, and outputs a signal according to the magnetic field formed by the permanent magnet and magnetic flux of a magnetic circuit including the magnetic yoke; a terminal that is electrically connected to the magnetic element; a case that is disposed around the magnetic yoke, and accommodates the magnetic element and the terminal; and an external housing that is formed of a resin material, accommodates the permanent magnet and the magnetic yoke, covers an outer side surface of the case, and is formed integrally with the case.
