Abstract
A torque sensor which can detect a torque with high accuracy is provided. First structure and second structure are connected by a plurality of third structures. First and second strain sensors are connected between the first structure and the second structure. Each of the first and second strain sensors includes a strain body connected between the first structure and the second structure and a plurality of sensor elements provided on the strain body. The sensor elements are disposed in a region of one side of each of the first structure and the second structure with respect to a longitudinal central portion of the strain body, and the region on the one side is a region where there is only a little difference in strain between along a torque direction of the strain body and a torque-excepted direction.
