A torque sensor includes a sleeve member configured to be mounted on a center shaft, and a tubular sensor body arranged coaxially with the sleeve member. At least one outer surface of the sleeve member includes one or more magnetostrictive elements. The tubular sensor body includes a bobbin for mounting a sensor coil. An induced current in the sensor coil is detected in response to pedaling by a user. The tubular sensor body includes one or more inclined surfaces inclined with respect to a radial direction of the torque sensor, the one or more inclined surfaces being coupled with the sleeve member or the center shaft.
