PROBLEM TO BE SOLVED: To provide a coil whose space factor can be improved by increasing the integration of conductor base wires forming a flat wire.SOLUTION: A coil 10 is formed by winding a flat wire 20 which has, on each of its both end sides in a thickness direction X, a lamination face 21 with a width greater than the thickness. The flat wire 20 is wound along a spiral axis direction in such a manner that a spiral face is formed by the lamination face 21. The flat wire 20 is formed by arranging, along a width direction Y, a plurality of conductor base wires 50 which are narrower than the lamination face 21. Among the plurality of conductor base wires 50, a pair of conductor base wires 50, 50 facing each other in the width direction Y of the flat wire 20 are provided with fitting means 70 for fitting the pair of conductor base wires 50, 50 to each other.

PROBLEM TO BE SOLVED: To provide a method for forming an Sn alloy thin film which has adequate solderability (low melting point) while preventing a whisker from forming, and has thin and uniform thickness. SOLUTION: The method for forming the thin film of the Sn-Ag-Cu ternary alloy on a substrate comprises immersing the substrate into a plating bath and electroplating it to form the thin film of the Sn-Ag-Cu ternary alloy on the whole area or a part of the substrate. The plating bath includes at least an Sn compound, an Ag compound, a Cu compound, an inorganic chelating agent and an organic chelating agent. The inorganic chelating agent is blended at a ratio of 1 to 300 pts. by mass with respect to the Ag compound of 1 pt. by mass, and the organic chelating agent is blended at a ratio of 1 to 200 pts. by mass with respect to the Cu compound of 1 pt. by mass.

PROBLEM TO BE SOLVED: To provide a conductive sheet for a non-contact IC card with a built-in antenna whose electric connectivity is highly reliable, whose circuit pattern formation is satisfactory, and whose producing efficiency is satisfactory. SOLUTION: This conductive sheet for a non-contact IC card with a built-in antenna is constituted by forming conductive layers on both faces of an insulating substrate, and electrically connecting the conductive layers on both faces through a through-hole or via-hole opened so as to be put through the insulating substrate. The conductive layers are directly formed on the insulating substrate, and configured in the same way on the wall face of the through-hole or the inside of the via-hole and on both faces of the insulating substrate, and the conductive layers constitutes a circuit including an antenna.

PROBLEM TO BE SOLVED: To provide a conductive sheet where an insulating film and a conductive layer have sufficient coherency, and hence the separation of the insulating film from the conductive layer is prevented, the thickness of the conductive layer becomes moderate, and a pattern can be fined. SOLUTION: In the conductive sheet, the conductive layer is formed on at least one surface of the insulating film. The insulating film contains a filler, or a layer containing the filler is formed on at least one surface of the insulating film. The filler is removed by etching treatment for allowing the surface to be subjected to roughening treatment, and the conductive layer is formed on the surface that has been subjected to the roughening treatment.
