In a torque sensor of a torque detection system, in a state where a torque is not generated, a first magnetic detector (61) overlaps with one, such as an N-pole, of a plurality of magnetic poles of a magnet (30) when the one of the plurality of magnetic poles of the magnet (30) is radially projected onto the first magnetic detector (61). A second magnetic detector (62) overlaps with another one, such as an S-pole, of the plurality of magnetic poles when the another one of the plurality of magnetic poles is radially projected onto the second magnetic detector (62). A motor control device, which corresponds to a calculation processor of the torque detection system, is configured to calculate a sum of a value, which relates to a detected strength of a magnetic field detected by the first magnetic detector (61), and a value, which relates to a detected strength of the magnetic field detected by the second magnetic detector (62). The motor control device is configured to calculate a steering torque based on the sum.
