Patent attributes
A sensor coil serving as a sensor unit fitted and retained in a sensor retaining hole of a sensor housing and a circuit board stored in a board chamber provided inside the sensor housing are integrated by coating the outer surface of a lead and the circuit board with a resin layer formed by resin molding performed under the condition in which the sensor coil and the circuit board are connected with the lead. As a result, mounting of the sensor unit and the circuit board of a torque detecting apparatus in the housing is facilitated, the reliability of the connection part of the sensor unit and the circuit board is increased, and occurrence of connection defects due to the function of external force is prevented.
