A spiral cable device is provided with a cylindrical casing, an inner cylinder rotatable relative to the cylindrical casing, and a flexible flat cable connected to the inner cylinder at one end thereof and to the cylindrical casing at the other end thereof. The flexible flat cable has plural leads arranged in a single layer and is folded to form multiple layers of the leads, so that even where the flexible flat cable is to have many leads, the spiral cable device can be made short in the axial direction thereof.
