A rotor-side lead block integrally holds a plurality of external connection terminals electrically and directly connected to a connection land of a first sub FPC. The first sub FPC is housed and fixed in the rotor-side connector portion. The external connection terminals and the connection land of the first sub FPC are connected to each other via solder. The first holding member holds the connection land of the first sub FPC between the rotor-side lead block and the first holding member.
