Provided is a rotary connector device capable of reliably suppressing a decrease in electromagnetic compatibility caused by electromagnetic noise and stabilizing impedance while suppressing an increase in size of the device. A rotary connector device (1) is provided with a fixed-side housing (10), a rotary-side housing (20) which is rotatable with respect to the fixed-side housing (10), and a plurality of flat cables (30) which are formed by covering a conductor with an insulating material and which are housed in a stacked state in an annular housing space (S) formed between the fixed-side housing (10) and the rotary-side housing (20), among the plurality of flat cables 30, a shielding film 35 is disposed between at least a first flat cable 31 including a first communication circuit conductor 31a5 and a second communication circuit conductor 31a6 and a second flat cable 32 adjacent to the first flat cable 31.
提供抑制装置的大型化、且同时能够可靠地谋求电磁噪声造成的电磁兼容性降低的抑制及阻抗的稳定化的旋转连接器装置。旋转连接器装置1具备:固定侧壳体10、相对于固定侧壳体10旋转自如的旋转侧壳体20、和多根扁平电缆30,扁平电缆30通过由绝缘材料覆盖导体而形成,以层叠的状态被收容在形成于固定侧壳体10与旋转侧壳体20之间的环状收容空间S中,其中,多根扁平电缆30之中,至少在包含第一通信电路用导体31a5及第二通信电路用导体31a6的第一扁平电缆31、与同第一扁平电缆31邻接的第二扁平电缆32之间配设有屏蔽膜35。
