A cable connection structure includes cables and a substrate having an electrode thereon. The cables are configured to be connected to the electrode. Each cable includes: a core wire formed of conductive material; a tubular inner insulator for covering an outer circumference of the core wire; a shield which extends along a longitudinal direction of the inner insulator and includes conductors for covering an outer circumference of the inner insulator, and has an exposed portion for exposing the inner insulator; and an outer insulator for covering an outer circumference of the shield. The shield including a region where the exposed portion is formed, the inner insulator, and the core wire are exposed in a stepped manner toward a distal end of each cable. The substrate includes a first electrode configured to be electrically connected to the core wire, and a second electrode configured to be electrically connected to the shield.
