A torque detection device includes: a magnetic flux collecting unit (40), and a sensor housing. The magnetic flux collecting unit (40) includes a holder (50), first and second magnetic flux collecting rings (41, 42), and a magnetic shield (60). The holder (50) has upper and lower through-holes (55, 56). The first and second magnetic flux collecting rings (41, 42) are fitted to an inner periphery (51X) of the holder (50). The magnetic shield (60) is fitted to an outer periphery (51Y) of the holder (50) so as to cover the through-holes (55, 56). The sensor housing is formed integrally with the magnetic flux collecting unit (40) by supplying resin onto an outer periphery of the magnetic flux collecting unit (40). The holder (50) has a resin flow passage (59) in its outer periphery (51 Y). Resin that is supplied at the time of forming the sensor housing flows into the through-holes (55, 56) through the resin flow passage (59). |
