A rotary connector including a structure for connecting a flat cable to a lead block. The lead block includes a plurality of parallel joint conductors extending through a resin member. A pair of holding arms extend perpendicularly from the resin member. A window is formed in the resin member through which portions of the joint conductors are exposed, and a pair of projections are provided adjacent the window. The flat cable includes parallel conductors sandwiched by insulating films. A connecting portion of the insulating films is provided at a leading end of the flat cable, and alignment holes are formed in the connecting portion. Portions of the conductors are exposed between the flat cable and the connecting portion, and grooves are formed in sides of the flat cable adjacent the exposed conductor portions. When the flat cable is attached to the lead block, the projections are inserted in the alignment holes formed in the connecting portion, and the holding arms are bent into the grooves to fixedly connect the flat cable to the lead block. The conductors of the flat cable are then welded to the joint conductors of the lead block through the window.
