A torque detection system that is less likely to affect external equipment is provided. A sensor IC (70) in a torque detection device (40) includes: a magnetic detection element (81) with its output voltage changing in magnitude in accordance with the amount of twist of a torsion bar; and a processing device (85) that converts the output voltage into an output signal switched between a low level L and a high level H. The processing device includes a signal generation device (87) that forms inflection points P1 to P4 in order to reduce a change speed during a rising period T1 when the output signal is switched from the low level L to the high level H or a change speed during a falling period T3 when the output signal is switched from the high level H to the low level L.
