A torque detection device capable of suppressing intrusion of static electricity into a magnetism collection holder and an electric power steering system that includes the torque detection device are provided. A magnetism collection unit (70) includes magnetism collection rings (71a, 71b), first and second magnetism collection holders (72a, 72b) that hold the magnetism collection rings (71a, 71b), respectively, and a magnetic shield (80) that covers the outer peripheries of the magnetism collection rings (71a, 71b). The inner peripheral surface of the first magnetism collection holder (72a) is provided with recessed portions (78). The outer peripheral surface of the second magnetism collection holder (72b) is provided with engagement protrusions (77) to be inserted into the recessed portions (78). The inner peripheral surface of the second magnetism collection holder (72b) is provided with recessed portions (101). The inner peripheral surface of the first magnetism collection holder (72a) is provided with protrusions (100) that project toward the second magnetism collection holder (72b). The protrusions (100) are inserted into the recessed portions (101) when the first magnetism collection holder (72a) and the second magnetism collection holder (72b) are assembled to each other.
