A torque detection apparatus 34 includes a magnetic element 61, 62 that outputs a signal corresponding to a magnetic flux from a magnetic circuit including a magnetic yoke. The torque detection apparatus 34 further includes a signal retrieval member 63 electrically connected to the magnetic element 61, 62, and a unit housing 43 formed of resin and molded integrally with the magnetic element 61, 62 and the signal retrieval member 63 so as to cover the magnetic element 61, 62 and the signal retrieval member 63. The unit housing 43 includes a body portion 50 provided with an internal space 86 in which the magnetic yoke is housed, and a connector portion provided with an internal space 75 in which an end of the signal retrieval member 63 exposed from the resin is disposed. In the unit housing 43, a communication path 87 is formed through which the internal space 86 is in communication with the internal space 75.
