ROTATING CONNECTOR DEVICE

Provided is a rotating connector device with which it is possible to suppress an increase in the size of the device, and to reliably suppress a decrease in electromagnetic compatibility due to electromagnetic noise and to stabilize characteristic impedance. A rotating connector device is provided with a fixed-side housing , a rotating-side housing which is free to rotate relative to the fixed-side housing , and a plurality of flat cables which are formed by covering conductors with an insulating material and which are accommodated in a stacked state in an annular accommodating space S formed between the fixed-side housing and the rotating-side housing , wherein a shield film is disposed at least between a first flat cable including first and second communication circuit conductors and a second flat cable adjacent to the first flat cable , among the plurality of flat cables
