A detection device includes a first rotating body, a first target fixed to the first rotating body, a first gear fixed to the first rotating body, a first magnetic detector element for detecting a rotation angle of the first rotating body, a second gear engaged with the first gear, a second rotating body having the second gear fixed thereto, a magnet provided at the second rotating body, a second magnetic detector element for detecting a rotation angle of the second rotating body, a third rotating body, a second target fixed to the third rotating body, a third magnetic detector element for detecting a rotation angle of the third rotating body, a torsion bar connected between the first rotating body and the second rotating body, and a controller operable to determine the rotation angle of the first rotating body and a torque applied to the torsion bar based on signals output from the first, second, and third magnetic detector element. The detection device detects an absolute rotation angle of plural turns and a torque.
