A torque sensor is provided with a coil whose inductance changes in accordance with variation in torque acting on an object. The torque is detected on the basis of the inductance of the coil. Specifically, the torque sensor includes a first oscillation circuit for detecting the inductance of the coil and for oscillating a signal having a period corresponding to the detected inductance. The period of the signal generated by the first oscillation circuit is detected by a period detection section. A torque detection section detects the torque on the basis of the period detected by the period detection section.
