A torque detection device that further suppresses intrusion of foreign matter into a magnetism collection holder and an electric power steering system that includes the torque detection device are provided. A first magnetism collection holder (72a) has a first ring portion (73) and a substrate housing portion (74). A second magnetism collection holder (72b) has a second ring portion (75) and a substrate housing portion (76). A pair of flanges (100, 101) are provided on both side surfaces of the substrate housing portion (76). The substrate housing portion (74) is provided with a partition wall (102) to be fitted between the flanges (100, 101). A substrate arrangement portion (110) is provided with a partitioning portion (105) and an extended portion (105a). When the substrate housing portion (74) and the substrate housing portion (76) are stacked on each other, the extended portion (105a) is fitted with a recessed portion (104). The substrate arrangement portion (110) is also provided with a partitioning portion (106). An extended portion to be fitted with the recessed portion (104) is provided at the distal end of the partitioning portion (106).
