Abstract: A first direction exposed conductor group includes a plurality of exposed conductor portions of a first flat cable, and a second direction exposed conductor group includes a plurality of exposed conductor portions of a second flat cable. The plurality of exposed conductor portions are located parallel to each other, and the plurality of exposed conductor portions are located parallel to each other. The first direction exposed conductor group and the second direction exposed conductor group intersect and overlap each other to form an intersection overlap portion. An intersection insulating film is provided between the first direction exposed conductor group and the second direction exposed conductor group at the intersection overlap portion. The exposed conductor portions and the exposed conductor portions facing each other via windows of the intersection insulating film are connected to be conductive to each other. Thus, an electric cable structural body is provided.

Abstract: The present invention has an object of providing a connection structure capable of easily connecting an LED component to a flat cable. An LED unit 1 includes an upper case 7, a pierce terminal 6, a lower case 9 and an intermediate terminal 5. An LED chip 3 is pressed to the pierce terminal 6 by a convexed spring 51 to electrically connect the LED chip 3 to the flat cable 100. Conductors 101 included in the flat cable 100 are formed of phosphor bronze formed of tin (Sn), phosphorus (P), copper (Cu) and unavoidable impurities and having a tensile strength of 480 to 550 MPa, whereas a pierce plate 63 of the pierce terminal 6 piercing through the conductor 101 is formed of a copper alloy, which is a high strength conductive member having a higher strength than that of the conductor 101 and having conductivity.
