To provide a torque detecting device capable of holding adhesion mechanically with electronic members by synthetic resin used to mold and having no possibility the synthetic resin may peel off from electronic members to form cracks.
The torque detecting device is equipped with a first shaft 1 and a second shaft 2 connected coaxially by a connecting shaft 3, a permanent magnet 5 fixed to the first shaft 1, a plurality of soft magnetic materials 4a and 4b fixed to the second shaft 2 to place in magnetic field of the permanent magnet 5, forming a magnetic circuit, a detector 6 detecting magnetic flux generated in the soft magnetic materials 4a and 4b, and an electronic member 19a connected to the detector 6, and, since the detector 6 and the electronic member 19 are molded by the synthetic resin 28a, is configured to detect the torque based on output from the detector 6 when torque is imposed on the first shaft 1 or the second shaft 2. The electronic member 19 has one or a plurality of open holes 18 which are filled up by the synthetic resin 28a.
