Abstract

A torque sensor includes a pair of magnetic yokes arranged in a magnetic field from a multipolar magnet that rotates integrally with, for example, a first shaft, and the magnetic yokes rotate integrally with, for example, a second shaft. The torque sensor includes magnetic collecting elements magnetically coupled to the respective magnetic yokes and a magnetic flux detecting element. The magnetic collecting elements have a pair of magnetic collecting portions (magnetic collecting protrusions) facing each other. The magnetic flux detecting element includes a circuit board with a cutout formed therein and a Hall IC having a Hall element arranged between the magnetic collecting portions, and the Hall IC is mounted parallel to the circuit board so as to extend over the cutout. At least a part of one of the magnetic collecting portions is arranged in the cutout.
