Abstract: In an electronic device, one end of a cable is on one side end surface in a third direction of a substrate extending in first and second directions. The cable includes a conductive wire, an insulating portion, and an opening portion. The conductive wire extends in the first direction. The opening portion is on the other end surface in the third direction of the insulating portion and opens at least to the other side in the third direction. One side end portion in the first direction of the conductive wire is drawn from the insulating portion to one side in the first direction, and is connected to the one side end surface in the third direction of the substrate. At least a portion of an adhesive on the one side end surface in the third direction of the substrate is in the opening portion.

Abstract: Disclosed are an adhesive composition for a metal foil which comprises a material wherein a tracking resistance test is carried out according to the IEC method by making a thickness of an adhesive layer 30 to 40 ?m, using a copper foil pattern with a width of 4 mm and making a distance between electrodes 0.4 mm, then the adhesive layer dissolves out for the first time when 5 drops or more of an electrolyte are dropped thereon, an adhesive-coated metal foil, a metal-clad laminate, a wiring board, a multi-layer board and a multi-layer wiring board using the same.
